Brad, could you leave the previous stable kernel available for download?
At least till you got some success messages?

I got one oops with the 2.6.32.14-patch, which causes X not to start (onboard intel gpu).
Right now I have to rebuild the kernel to include symbols.
Before I will report an error I will check if it's also present in the vanilla kernel.

The error seems not to be rpresent in the vanilla kernel.
I had to recompile the kernel again since I forgot to copy the vmlinux (after enabling the kernel symbols).

I've uploaded new patches that should resolve this problem. Thanks for the report.
