Rich,
Sorry I'm so late to the party. Anyways, ah good ol APIC...
Usually, it is pretty safe to enable APIC (even on uniprocessor)
machines by default these days. Most machines either have an APIC that
works or don't (in which case Linux won't try to use it). You are stuck
somewhere in the middle (it seems).
To see IRQ stuff in linux, execute "cat /proc/interrupts". If you have
any IRQs above 15, you are using APIC.
If you need to pass boot options with the CD, download the devel
tarball here:
http://mirror.astlinux.org/astlinux-devel.tar.bz2
And you will find the script to re-master the ISO.
