That should be a rarity these days, and probably a bug. More at issue
is really kernel compilation options (optimizations as well as 32/64
bits, and amount of memory.) One particular issue here is UP vs SMP,
which means being able to detect auxilliary processors; this can be done
via MP table or ACPI.

No, not since the bad old ISA days. These days you can do enumeration
much easier than you can do actual support, at least for the common
on-system busses (USB/Firewire gets a bit more complicated, but they
mostly have "class drivers" for anything important like storage.)
