I get that too... compiles and mostly works.

That pfn issue seems to affect my pointer device (Synaptic).
I've used both NVIDIA 7676 and the latest: 8174

Versions between 2.6.13-rc3 - 2.6.15-rc5 haven't worked (well.. I
hadn't tried out any 2.6.15 revisions until now).  I have 2.6.13-rc3
sitting back in case this pfn issue causes too much trouble.


Does anyone
