> Counted MMX_INSTR_RET events
Hmm, only MMX instructions were counted? That's not really what I wanted to
have, I don't know oprofile that well, maybe it's even not better possible with
the machine/cpu, maybe some other parameter needs to be passed?

This get's even stranger..., you can try to shut down all devices and rip out
all kinds of modules, maybe you find a bad one that produces the Load? Hmm,
Magnus probably does not have this card. Maybe it's the (uhci/ehci)_hcd driver?

Also try to set ACPI_MODULES="NONE" in /etc/sysconfig/powersave/common. If you
reboot also rip out the thermal and fan module. The only ACPI module that now
still exists is processor and cpufreq should still work? The system should not
notice anymore now whether AC state changes. If it works now, it's one of the
ACPI modules.

Hmm, I ask on the kernel list about the wrong process acounting...
