Check compat-wireless; IIRC LP-PHY rfkill support has been updated in 2.6.34.

BTW, does software-rfkill (using the rfkill command-line utility) work
correctly?
Specifically, the following scenarios are interesting:
-With the hardware-rfkill switch ON (i.e. radio enabled), try to bring
down the card using the rfkill utility. Does the card actually stop
transmitting?
-Try to turn it back on. Is the interface usable again?
-Turn the hardware switch OFF, and back ON. Then, use rfkill to
soft-disable and re-enable the card. Does this make it work again?
