I'm using Fedora's 2.6.8-1.521 kernel source plus .config with some
changes (added driver for my web camera, comment out the Latitude
blacklisting in arch/i386/kernel/dmi_scan.c, and config changes to turn
on APIC, OProfile, and the webcam driver).

It does indeed say "i386/p6_mobile". How interesting. I didn't think
the module was loading (I thought the error was fatal). Maybe it's the
daemon that's spitting out the errors. I just tried opcontrol
--start-daemon and it doesn't seem to fire up the daemon.
I'm wondering: Looks like the userland stuff is somewhat old (CVS
version around January 2004, not the official release from May 2004).
Maybe the errors are due to bugs in the userland stuff that have since
been fixed? I wonder why the Fedora crew hasn't updated the RPM... Is
there a newer RPM available somewhere?
