That's weird:Something strange happened, I shall try 2.6.4-mm1 shortly to see if it is still the same. I reckon though that I've suffered a filesystem corruption.

$ lsmod | grep nv

Running KDE, using kdm, with nvidia module, no problem, I notice a slight difference on fonts, but I dont know if it's my imagination.
Been using nvidia modules for quite a few 2.6.x kernels, most of them mmX. without problems
