Description Kay Sievers 2012-08-03 11:36:33 UTC 
There should be no need to load microcode explicitly, the recent CPU
aliases should take care of loading all CPU specific modules. Please drop
the rules file entirely.

$ cat /sys/devices/system/cpu/cpu0/uevent

Comment 1 Anton Arapov 2012-08-06 09:02:10 UTC 
True. I did the necessary modifications upstream already, a week ago or so. I will push them to Fedora rawhide soon.
