Doing image decoding in the bios seems particularly pointless.  Why don't you 
just pass the bios raw image data?

If you really want to directly support fancier formats IMO it makes much more 
sense to do that in qemu itself.  There we can use the same libraries as 
everyone else (libjpeg, libpng, etc) rather than badly reimpleenting them 
inside the bios.
