When I try to run the latest nVidia installer it complains that:
"No precompiled kernel interface was found to match your kernel, would you like
the installer to attempt to download a kernel interface for your kernel from the NVIDIA
ftp site?" I answered yes, but it could not find one.
I later actually visited the nVidia site and browsed through thier ftp file hierarchy,
and sure enough, there is no interface for 2149.
If you just continue through the installer one more step past the "attempt to download a kernel interface for your kernel..", the installer will compile a custom kernel interface matching your kernel.
