Perhaps it will be fixed in centos 5.4

do you have the latest BIOS on that board?   looks like they have 
released several updates, latest being 2102 (assuming its the basic p5q 
and not one of hte innumerable proturbohyper++ versions)
.   This wouldn't be the first time an Asus board has had bad 
PCI/ACPI/etc data structures in its BIOS.

googling for that error indicates if you're running xen, its totally 
bogus, if you're running a regular kernel, its an indication of a BIOS 
problem, but it should have no impact on your system operation or 
performance.
