happily that doesn't matter i01 as the patch still works. It patches the nvidia files not the kernel. Ocasionally it gets broken but it is quickly fixed.
I use 2.6.0-test9-bk7 at the moment, works perfectly. I guess to reflect this the labels have been tweaked recently to just 2.6 eg 'NVIDIA_kernel-1.0-4496-2.6.diff'
P.S. bk stands for bitkeeper, it's check it out at http://www.bitkeeper.com/
Basically bk snapshot are the bleeding edge releases of the linux kernel.
