if i'm reading the output you've sent correctly, linux is getting
the interrupt mappings from ACPI not the MP table. and your
mp table is broken.  i don't know very much about linux irq
handling or acpi irq tables, but it's likely that your mb manufacturer
didn't think a full mp table was worth his time.

so, i guess this is the menu of options in increasing amount
of effort and accomplishment:

1.  *nomp=1
2.  bios update.
3.  figure out what the mp table should be from the acpi
tables and forge an mp table for archmp's benefit.
4.  teach plan 9 to parse the acpi irq tables.

cheer up!  the acpi documentation is less than two feet
thick.
