PCI works on Canyonlands without any problems. I just tested latest Linux 
release (2.6.32) with an PCI USB card:

-bash-3.2# uname -a
Linux canyonlands 2.6.32 #1 Fri Dec 4 05:42:35 CET 2009 ppc ppc ppc GNU/Linux
-bash-3.2# cat /proc/cpuinfo

I can't see any problems with PCI interrupts here.

Cheers,
