Ben, I see you have this queued up in you 'next' branch, but this seems to be
impacting 2.6.32 and according to the comments won't be needed in 2.6.33.
Right now, 2.6.32 doesn't build for a general Fedora ppc32 kernel because of
this bug.  Should this be sent to Linus for .32?

for the curious among you that want to look at the build log)
