Martin Peres, Hi!

Any update on this support?

The old patch of yours that works fine on my card surely doesn't apply
to latest git. I am going to forward-port it so I could switch to next
kernel, but I was thinking that maybe you have a new version of this
patch, so I won't waste my time.
Without this patch, reclocking is very very unstable as you know, but I
need it to keep card temperature within reasonable bounds.

(And pref level 0 gives me ~50 FPS in compiz....)

Speaking of performance, offtopic, nouvaeu + kwin isn't usable at all,
but compiz really is.

Kwin on the other hand is dead slow even on perf level 2, and
surprisingly, even if I start compiz in KDE it is significantly slower
that same compiz in Gnome (but usable).

And when I move mouse over any Qt application, FPS drops below 5 FPS,
probably due to mixture of Xrender and GL calls.
So nouveau + kwin is absolutely not usable.

compiz + gnome without any open windows shows ~300 FPS on perf level 2
slightly higher that nvidia blob.

I own quite slow card, nvidia geforce 8400M GS, codename NV86

I am looking forward to switch to KDE in near future.
