The sanity check is simply there because I had no test case
which patches the vendor id. How could I test with vga bios?

No trivial way as the vgabios needs to be patched to handle that.

patchrom branches available now:


very short instructions:

(1) fetch+compile vgabios, copy new vgabios-pci binary
    so qemu can find it.
(2) fetch qemu, apply/merge id patching, compile qemu
(3) both standard and vmware vga should happily work
    with the same vgabios binary now, including vesa
    graphic modes.


Hi Gerd,

a new patch which also modifies the vendor id will follow
immediately. Perhaps you can try it with your modified vga bios.
