Where did you stick the checksum?  Did you compute a checksum?

Also the X driver code you posted outputs the value when its in error.
 You should just be able to change the last byte of your vbios image
to whatever the X driver outputs.

For fill files I either do something like Kevin suggested or just
create one with cut and paste in a hex editor.  I always have some
32k, 64k, and 128k files of just 0xff that I use to [ap,pre]pend to
the file with 'cat'.  Also my flash programmer will do fills.
