Keith:

I learned of the new driver release just last night, and I'm also working 
to complete the manual extraction.  You're actually a little bit ahead of 
me.

It looks like the cpufw fetch command didn't "take".  Unfortunately I'm 
not in a position to diagnose it right now.  I should get a chance to 
chase this in about 13 hours from now.
