I'd like to see what you read. In my experience it either works or it
doesn't. One can't avoid using APIC interrupts in a dual-processor
system.

Yes, that HOWTO has good info, as far as it goes. One thing I would add
though, is that when using non-APIC interrupts the interrupt priority is
not fixed in stone (or silicon, as it were). Using the program
"irqtune" one can change interrupt priorities (see
http://www.best.com/~cae/irqtune ). I havn't used irqtune in a while,
not since kernel 2.2 days, so I'm not altogether sure that it works
correctly with 2.4.x kernels. On Debian it is in the "hwtools"
package. Hmm, I just tried it on a box with a 2.4.21+lowlatency kernel
and it seems that it worked, though it gave some warnings. I can't
really test if the IRQ priorities have changed though. YMMV.
