I tried madwifi-0.9.4 snapshot on a CM9 card, and I got:
# iwpriv ath0 get_abolt
ath0 get_abolt:218
218 is 0xda, which means that the following capabilities are enabled:
IEEE80211_ABOLT_TURBO_PRIME
IEEE80211_ABOLT_FAST_FRAME
IEEE80211_ABOLT_BURST
IEEE80211_ABOLT_XR
IEEE80211_ABOLT_AR
And those are not enabled:
IEEE80211_ABOLT_TURBO_G
IEEE80211_ABOLT_COMPRESSION
IEEE80211_ABOLT_WME_ELE
I would just unset all capabilities and retry.
