Default Problems with 2.6.20 and SLI

Hi Everyone,

I have some problems after upgrading from kernel 2.6.18 to 2.6.20. After the upgrade my SLI Cards donīt work in SLI mode.
Here the output of my /var/log/xorg.log
--snip--
(WW) NVIDIA(0): DamageEvents are not currently compatible with SLI. Disabling
(WW) NVIDIA(0): DamageEvents.
(EE) NVIDIA(0): Failed to find a valid SLI configuration!
(EE) NVIDIA(0): Invalid SLI configuration 1 of 1:
(EE) NVIDIA(0): GPUs:
(EE) NVIDIA(0): 1) NVIDIA GPU at PCI:2:0:0
(EE) NVIDIA(0): 2) NVIDIA GPU at PCI:7:0:0
(EE) NVIDIA(0): Errors:
(EE) NVIDIA(0): - GPU video memory sizes do not match
(WW) NVIDIA(0): Failed to find a valid SLI configuration for the NVIDIA
(WW) NVIDIA(0): graphics device PCI:2:0:0. Only one GPU will be used for
(WW) NVIDIA(0): this X screen. Please see Appendix W: SLI and MultiGPU
--snap--

The error is very funny, because both cards are exact the same.
lspci:
02:00.0 VGA compatible controller: nVidia Corporation G70 [GeForce 7600 GT] (rev a1)
07:00.0 VGA compatible controller: nVidia Corporation G70 [GeForce 7600 GT] (rev a1)

I use the latest nvidia driver 9749. And as I told before, with the 2.6.18 everything is working fine. But I need to use the 2.6.20 kernel, because I need the new ALSA version included in 2.6.20.

Any Ideas?

P.S. What are "Damage Events?"

P.P.S. Hereīs my xorg.conf:
