A pointer to ACPI tables. It can reside in multiple places.

This one succeeded, so no problem here.

This is the APIC ID->Name translation. .19 didn't have P4 Xeon in the

IO-APIC isn't in the whitelist in 2.4.19
This is ok, as it still gets used. .20rc1 should have this fixed.

And that's not 'cool' enough ? 8-)
If there are only 2 physical CPUs there, then this is working fine.
2.4.20rc2 will also print nice things in /proc/cpuinfo for you.
