If I turn off CONFIG_X86_UP_APIC I get:

and ACPI is disabled. Halt doesn't work.

If I then pass `acpi=force' to explicitly enable ACPI, `halt' works again
and powers off the machine, but `reboot' causes a black screen with IDE
disk spun down, but no restart.

Gr{oetje,eeting}s,

My PIII 650 with 2000 BIOS boots linux with acpi disabled for the same reason, 
unless force ACPI support. It reboots fine with ACPI forced. The ACPI support 
of this Intel BX mobo is good, so this is a false negative IMHO. (I wonder if 
the check is correct, shouldn't it say 2000 instead of 00 ?)

If year < 90 it adds 2000 so that's OK. But the code needs ACPI from 2001 or
more recent, so my BIOS from 2000 fails...
