FWIW, this also occurs consistently in F12 as well with all the latest updates with the exact same hardware as jlaska (macbook pro). Please let me know as well if there is any additional info you need from me as well as any possible workarounds you may know of. The only way I have been able to re-enable brightness control it seems is by rebooting.

This bug appears to have been reported against 'rawhide' during the Fedora 14 development cycle.
Changing version to '14'.

Hi, James. Is this still valid with current F13/F14? Thanks.
