I have an HP _desktop_ with an ATI chipset and a dual-core 3800+ that
exhibits this. If your patch just inhibits output for machines with
one logical CPU, it won't be inhibiting it on mine. I'm seeing:

powernow-k8: error - out of sync, fix 0xa 0x2, vid 0xa 0x12
APIC error on CPU0: 00(40) # once, at boot
APIC error on CPU0: 40(40) # repeated regularly after boot

Yes, my machine exhibited this bug in earlier 2.6 releases. Passing
enable_timer_pin_1 fixed it for me before the chipset detection was
brought into mainline. Now that it's fixed, I still see the errors
above; while both problems are caused by ATI's bizarre chipset, the
error doesn't mean that double time is happening.

My dmesg and lspci are attached, let me know if you'd like anything
else. The machine's an HP Pavilion A1250N.
