Default Strange gentoo behaviour


I just want to ask, Is there anyone, that have problem with "kernel path
slowdowns"? I think that this is made by i965GMA graphic card with GEM
support under 2.6.28 Kernel (bare, vanilla and gentoo sourcess). I've
tried Intel's patches from www.intellinuxgraphics.org but this also
don't work. I'm pasting message log and GCC version strings.

Thing's get worse because of strange freezing system time to time.
Yesterday I was thinking about AC'97 audio problems because of freezing
when amarok 2 plays audio, but without amarok things are also bad!

What to do? Kernel from intellinuxgraphics page also don't work. I have
Mesa 7.2 downloaded from intellinuxgraphics because of fact that
gentoo's mesa don't work good - it work's slow, i don't know how.
DRI/DRM is provided for me by libdrm and drm modules from
intellinuxgraphics because of DRI/DRM v.2 (read GEM, not Tungstren
Graphics TTM buffer manager) compatibility. I know that 2.6.28 have GEM.
