It does work but the lowest brightness in auto is often too low (value of 1 notch in manual mode) so I've resorted to using notch 4 in manual mode, it's the best brightness for indoor and outdoor use I find until autobrightness is upped to Sense ROM levels.
DeFrost on occasion has this issue too as do most other AOSP ROMs.
