You need to enable smp in the kernel to get apic enabled. And use
maxcpus=1 if you only need one cpu running.

Yes I did.  I wasn't sure if I added them correctly, though.  I just
copied
most of the entries from another line and changed the major and minor
numbers.

It works for a different kernel through the filo etherboot pathway, so
I'm
wondering if I've misconfigured the kernel.  Do I need to explicitly
support
the Opteron?  I'm using a 32-bit kernel because there are no linux-tiny
patches for 64-bit.

Thanks. That solved the IRQ problem and I can mount a USB key formatted
ext2.  I still can't get my IDE HDD to mount, though.
