The above worked, but some of the modules in the drivers/hwmon from will not build on from F12.  I've not tried on F11
2.6.30.x yet.  I've written a Makefile.patch to fix the compile-time
issues and get as many modules as possible to build.  Should I just
concentrate the new kmdl on containing those modules specific for the
Intel Atom or should I include as many kmods as will build?   hwmon,
coretemp, lm90 are the primary modules I'm interested in for Intel
Atom support, but I could include the rest of the modules that also

What should the RPM be called?  hwmon and hwmon-kmdl?  For a snapshot
name I was using 2_6_32_8 temporarily.  Is there a proper way to
denote that I'm building hwmon drivers from a newer kernel release?
