Due to demand on the talk page, I have done some research on this piece. The following are the results with relation to the Köchel-Verzeichnis. Köchel numbers will be given in the format Keditionnumber
Köchel-Verzeichnis first edition (Published in 1862): Entire work not listed. A possible fragment of the work listed as K154 (theme and variations for piano).
Köchel-Verzeichnis third edition (Published in 1937, edited by Alfred Einstein): Entire work listed as K3547a. It is also listed as being made up of Anh135 and Anh138a, with a note that Anh138a=K154. The work is listed as having three movements, the first two are fast (Allegro/Allegretto), the third being the Andante theme and variations listed as K154 or Anh138a. The entry for K354 has become a stub, which points to K3547a ("K.54 = K.547a").
Köchel-Verzeichnis seventh edition (Published in 1965, edited by Franz Giegling, Alexander Weinmann, and Gerd Sievers): Entire work listed as K7547a. It is also listed as being the same as Anh135. The work is listed as having two movements, both of which are fast. The two movements of K7547a are identical to the first two movements of K3547a. However, the third movement of K3547a (i.e. the Andante theme and variations, also known as K154 or Anh138a) is NOT listed as part of this work, but rather as K7547b. The entry for K754 is also a stub, which points to K7547a ("K.54 = K.547a"). This is clearly an oversight on the part of the editing team, since it should point to K7547b.
It is clear that this work is not a major work, and is not very clearly defined. An interesting sidenote must be made with regards to the relationship of this work to Kall547, which is a three movement violin and piano sonata. In the third edition of the Köchel, both pieces share the same third movement (i.e. K154 or Anh138a, except transcribed for violin and piano in Kall547), with the other two movements being completely different. In the seventh edition of the Köchel, the two works do not share any movements, and thus K7547a is an entirely different piece from Kall547, contradicting rumors to the contrary.
Also, as a result of this research, the label of "complete score" will stay with IMSLP #00227, since it is listed as having only two movements in the latest edition (seventh) of the Köchel-Verzeichnis that I have access to.

Someone changed the status of IMSLP #00227 to "fragment" with the note that it is "missing the 2nd and 3rd movement". First of all, there IS a second movement in the PDF: it starts at the bottom of page 7. Also, I see no support whatsoever that the piece has more than 2 movements; the fact that the second movement is fast does not support the idea of a third movement. Unless I see some proof that there are additional movements, the designation of "complete score" will stay with IMSLP #00227. -- Feldmahler 13:19, 5 April 2006 (CDT)
I have studied the Köchel-Verzeichnis, I have played Mozarts sonatas (among them KV. 547a) and I have incidentally noticed a third movement if not more. iIf that does not convince you (which I am certain it does not), I have been generous to attach a link to the KV. 547a sonata: http://www.angelfire.com/tn3/papazacharias/Mo_K547.mid

Thank you for the link. I will do some more research about this sonata, including the definite number of movements. Also, this sonata is possibly not first written as a piano sonata, but is later transcribed into one by Mozart himself, so there may very likely be discrepancies with different editions. I will give the research results at the end of the weekend. --Feldmahler 18:55, 6 April 2006 (CDT)
I have finished my research, and you can see it on the main page of the work. Hope you are satisfied with the results. --Feldmahler2 14:07, 8 April 2006 (CDT)
