Nowy kernel a grafika 3D

[Grzegorz Żarnowiecki]

Witam wszystkich, po ostatnim upgrade kernela i okolic pojawił mi się ciekawy 
problem, wydajność grafiki 3D spadła o x% (armagerton przed upgrade do 200fps 
po upgrade do 4fps)
aktualnie mam coś takiego:

[root w pa2 zet]# rpm -qa |grep  kernel
kernel-i2c-2.8.2-1 w 2.4.24_0.3
kernel-sound-alsa-1.0.1-1 w 2.4.24_0.3
glibc-kernel-headers-2.6.0.4-1
kernel-headers-2.4.24-0.3
kernel-2.4.24-0.3
kernel-video-nvidia-1.0.5328-1 w 2.4.24_0.3
kernel-i2c-lm_sensors-2.8.2-2 w 2.4.24

i dodatkowo
XFree86-4.3.99.901-0.1
XFree86-driver-nvidia-1.0.5328-2

<tutaj inne nie dotyczące>

kernel: 0: NVRM: couldn't find pre-allocated memory!
(To sie powtarza co jakiś czas)

Przed upgrade było 2.4.22 samodzilenie kompilowane z CVS + niezbędne dodatki z 
tego samego źródła.
Karta to Geforce2MX400
Goglowanie nic nie przyniosło, myśle nad downgrade ale może się uda uniknąć ?
Dzięki za pomoc
