I suspect that this is either a bug or an extension specific to the 
vendor of your SVGA.  Since the Interrupt List says that AH=1 signals an 
error, and you get AH=80 (is it 80 hex or decimal, btw?), I suggest to 
try to treat it as successful return, and see whether the rest of the 
functions work.

For more confidence, you could use functions 4F00h and 4F01h, which
return similar information, and see whether 4F03h is consistent with 
them.
