"leads system to segmentation faults"
So trying to use powersave features makes random applications crash?

Exactly!:)
Sorry for my english - a little bit out of practice...

This looks like hardware issue (we can do nothing here).

[Comment 4 Jeroen Roovers (RETIRED) 2010-02-22 18:57:00 UTC]

Please attach dmesg and /proc/cpuinfo output.

Please get back to us (also try with a newer kernel like 2.6.32 or 2.6.33)
