OK - thanks. The patch seemed to install correctly. I then did

make clean
make && make modules_install

and then a Gentoo command:

modules-rebuild -X rebuild

to pick up any package modules that need to be rebuild when I use a
new kernel. (X drivers, vmware, etc.)

The kernel boots fine:

mark@...table ~ $ uname -a
Linux c2stable 2.6.34-gentoo-r1 #4 SMP PREEMPT Tue Jul 6 10:35:15 PDT
2010 x86_64 Intel(R) Core(TM) i7 CPU X 980 @ 3.33GHz GenuineIntel
GNU/Linux
mark@...table ~ $

I don't know what I'm looking for in the dmesg files but I do see one
message about a SATA Link being down.

Files attached.

Cheers,
Mark
