E.g. PCI spec, page 297, gives an example of such a device: Programming interface 0000 0000b VGA-compatible controller. Memory addresses 0A 0000h through 0B FFFFh. I/O addresses 3B0h to 3BBh and 3C0h to 3DFh and all aliases of these addresses. While we could check for these devices and special-case them, it is easier to fix this by enabling i/o and memory space unconditionally: devices that do not support it will just ignore this setting.

This is for qemu-kvm.git to get pcbios consistent with seabios.
--- This patch is needed for qemu-kvm as that is still using pcbios.Why hasn't qemu-kvm switched to seabios?
Regressions. AFAICT all have been fixed now, and the switch is imminent. -- error compiling committee.c: too many arguments to function
