And one more time! I have re-installed kernel-2.6-source and followed the steps in that first message in the thread - make mrproper, copy /boot/config-2.6blahblah to /usr/src/linux-2.6/.config , make oldconfig, make prepare, make scripts - and now nvnet compiles and works properly, so I'm writing this from kernel 2.6! So we need somehow to have the kernel source prepared in the way those steps make it, as packaged, or people will not be able to build external modules against it without looking up the stuff as I did. nvidia still doesn't seem to want to work, though - compiles with no errors, loads into the kernel with no errors, but doesn't work when I actually try and start X (says it failed to initialise the kernel driver). I'll look into that one, too... -- adamw
