Leigh Scott (leigh123linux) has already produced an NVIDIA driver patch for 304.30 to compile – and run – on kernel 3.6-rc1..   Get it at:

http://cvs.rpmfusion.org/viewvc/rpms/nvidia-kmod/devel/3.6_kernel.patch?revision=1.2&root=nonfree&view=markup

I’ve applied the patch, and all is OK, now…     So – 3.6-rc1 now works, with VMware 8.0.4 (patched) and NVIDIA 304.30 (patched)…
