And I like the idea of chosing a solution that won't limit us to x86 hosts anyway ;)
With proper support from the "VGA arbitration driver" that Jon talked about earlier, that should be quite portable, the kernel driver doing the job of providing PIO accessors to VGA space and mmap functionality for VGA memory hole if it exist (can modern cards be POST'ed with an x86 BIOS on machines that won't let you access any VGA memory hole, that is that won't let you generate PCI memory cycles to low addresses that overlap RAM ? If yes, then pmacs would be able to soft-boot x86 cards that way).
