Evgeny's (eumaster) and Uli's chipsets are both:

north-bridge: nvidia c51mv
south-bridge: nvidia mcp51m

Also both are MSI laptops:
- MSI-M670, modell MS-1632
- MSI S430x
(This could also be a chipset or even an MSI specific BIOS bug?
Richard could you compare with your HW, pls if still possible).

Some more info:
- things break entering C2 or deeper
- noapictimer workaround helps to come a bit further, but results in sever
other errors, disk(dma error), keyboad, mouse etc., also see:
https://bugzilla.novell.com/show_bug.cgi?id=396220#c13
- "nohz=off" works (tested on 2.6.25.4-8-pae and 2.6.22.17-0.1-default SUSE kernels)
- processor.max_cstate=1 works
