Kconfig was all defaults except VGA ROM pieces (which are off
by default). I selected VGA_STANDARD_VGA, VGA_VBE, VGA_PCI and
left OVERRIDE_PCI_ID UNselected, since I didn't know what to
put there. Maybe the last item was my mistake.
The binaries were put into right place where qemu-kvm picked
them -- -bios /path/to/seabios/git/out/bios.bin, and vgabios.bin
into the standard qemu-kvm directory, as vgabios-stdvga.bin.
I think I learned where to put this stuff by now, after maintaining
Debian package of qemu-kvm for over 2 years... ;)
This is qemu-kvm 1.0, I haven't tried with current qemu git
version.
