Half and Quarter Channel Support??

I am trying to use a Ubiquity XR9 in Half and Quarter channel modes, but I 
cannot get it to work.

The managed stations sees the access point in half and quarter channel mode 
but they cannot associate to the AP. Works properly in full (20MHz) BW mode.

I've done a ton of reading on here and the web, but I can't seem to get a 
straight answer: Is Half and Quarter channel operation supported by Madwifi? I 
guess particularly with the Ubiquity XR9 card. I spoke with the Ubiquity tech 
support guy and he tells me that Madwifi does NOT support 10MHz and 5MHz 
channels. Yet, I can get the Wiligear 2.4 cards to work in half bandwidth 
modes with Madwifi.... so confused now.

If so, any ideas what could be wrong?
