Arjan van de Ven is now building RPMS of the kernel and those can be found
in the RPM subdirectory and should be yum-able. Expect the RPMS to lag the
diff a little as the RPM builds and tests do take time.

* - already fixed upstream
X - discarded later as wrong
+ - ac specific (fix not relevant to non -ac)

Below is a cut from the 2.6.10-ac2 patch. I think since
pci_find_device() == NULL is more unlikely, please consider this patch
previousely posted on your original thread:

Suppose index is 0 or 1, pci_find_device calling could be avoided also.

PWC can only be build as module. I've patched it to be build
into the kernel. The patch is attached.
