Bug#573048: hostapd incompatible with 2.6.33 kernel

[David]

Read on debian osdir.com/ml/debian-bugs-rc/2010-03/msg00474.html I can 
confirm this (using kernel 2.6.33, and ath5k)

This article mentions version 0.6.10, getting:

Mode: IEEE 802.11g Channel: 6 Frequency: 2437 MHz
Invalid argument
Could not set RTS threshold for kernel driver
wlan0: Unable to setup interface.

and I tried that version and got the same thing, along with the 
development version 0.7.1, which would not even compile with the nl driver:
$ make clean && make
   CC  ../src/drivers/driver_hostap.c
../src/drivers/driver_nl80211.c: In function 'family_handler':
../src/drivers/driver_nl80211.c:232: error: 'CTRL_ATTR_MCAST_GROUPS' 
undeclared (first use in this function)
../src/drivers/driver_nl80211.c:232: error: (Each undeclared identifier

in.)

Any ideas?
Thanks,
