First 1024 bytes ? hrm... that isn't much... doesn't seem to work much for me. I have a board with a Rage Mobility, ATI gave us a BIOS image, I've tried running it in an x86 emulator (it's a ppc machine) to no avail so far. That BIOS appears to be mucking around with all sort of things not directly related to the actual video chip, like strange IO ports all around the legacy space (more than just the timers) etc...
