Actually, I think part of the point is to be able to, for example, run
PCI expansion ROMs for video (or other) cards.  Some PCI video and RAID
cards need (x86) code run from their expansion ROMs for proper
operation.  At the moment, this isn't done in NetBSD, but it could
presumably be done with an x86 real mode emulator.

Joerg: How about src/sys/emul/x86 ?  I don't think it fits nicely in any
existing location.
