[2.6.0-mm2] PM timer still has problems

[Karol Kozimor <sziwan@hell.org.pl>]

Hi,
Booting with clock=pmtmr causes weird problems here (the system 
complains that clock override failed and the bogomips loop produces bogus
values). Below is the dmesg output as well as /proc/cpuinfo.
I have CONFIG_X86_LOCAL_APIC=y and CONFIG_X86_PM_TIMER=y.

I don't really know whether this box (ASUS L3800C, more data at
http://bugme.osdl.org/show_bug.cgi?id=1185) has a PM timer or not, but even
if it doesn't, the code should account for that gracefully.
I'll be happy to provide any additional info.
