 +compat-wireless-old currently disables support for 2.6.22 because of a kernel crash you get if its enabled. The oops is below and the exact line where it hits is showed as well: 
 +Using gdb to get the exact culprit: ​
 +<​code>​mcgrof@tesla /​lib/​modules/​2.6.22-15-generic/​updates/​net/​mac80211 $ gdb mac80211.ko
 +GNU gdb 6.8-debian
 +Copyright (C) 2008 Free Software Foundation, Inc.
 +License GPLv3+: GNU GPL version 3 or later <​http://​​licenses/​gpl.html>​

 +This GDB was configured as "​i486-linux-gnu"​...
 +(gdb) l *(wme_qdiscop_dequeue+0x120)
 +0x18a20 is in wme_qdiscop_dequeue (/​home/​mcgrof/​devel/​compat-wireless-2.6/​net/​mac80211/​ieee80211_i.h:​768).
 +warning: Source file is more recent than executable.
 +763     ​static inline struct ieee80211_sub_if_data *
 +764     ​IEEE80211_DEV_TO_SUB_IF(struct net_device *dev)
 +765     {
 +766             ​struct ieee80211_local *local = wdev_priv(dev->​ieee80211_ptr);​
 +768             ​BUG_ON(!local || local->​mdev == dev);
 +770             ​return netdev_priv(dev);​
 +771     }
 +(gdb) </​code>​
 +So line 768 is the culprit. ​
