the IRQ controller should see no difference compared to UP Linux, stock
2.1.84. The MCA IRQ controller is 8259A compatible, right, at least from
the I/O programming interface side?
but if the box is not MP 1.1/1.4 compatible then there will be problems.
best would be to first try an IO-APIC-less kernel, say 2.1.76. The IO-APIC
code currently assumes that the board has a 'IMCR' IO port ... dunno what
happens if there is some other way on the system to enable the IO-APIC.
