Maybe ACPI helps out here a bit. On i386 and ia64, where the ISA legacy rears its ugly head the most (I think), ACPI can be used to enumerate the legacy devices. In that sense I treat ACPI as a bus. The tricky part still is that there's a lot of assumptions about the BIOS and the BIOS data area that, if I understand correctly, goes beyond plain ISA and is best described as PC specific. I think this is more a driver issue than anything else. I think if we can tackle ISA or PC legacy fairly decently, we should have something that would work good in general. > This whole discussion shows that our tree is still to x86 centric > (with alpha hacks for extra lovin' goodness). With non-i386 platforms the common case now, I think it's time to bring the balance back.
