Have you tried MPACPI instead of MPBIOS? Some Dell machines make our ACPI
code freak out -- but that is a bug that should be fixed, and in general
the ACPI code has a much greater chance of working on machines with
complicated interrupt routing and many buses, I think. Some machines will
probably not even *have* MPBIOS in the future.
Your time would probably be better spent making MPACPI and the various
ACPI_XYZ_FIXUP options work on this machine than trying to get the MPBIOS
code working. :-/
Of course you could always run NetBSD under Xen ;-) ;-) ;-)
