I do not solved this problem.
I already tried with named 'pci1002,791f.rom' for vbios file. But it can not help.
I acquired this vbios file from AMD which is customized for my mainboard.
From the original report:

It appears that the vga bios is trying to call some custom function of the main bios. This may prevent SeaBIOS from running the rom. Maybe with documentation on what "int 0x15 ah=4e" did on your board you could implement the logic in seabios.
