Dlink DWA-556 under rhel 5.5 not getting IP address

I have a Dlink which works great under Windows 7 64 , but under rhel 5.4,
no go.  There wasn't any 64 bit support for NDIS or any support in
madwifi.

I just upgraded to rhel 5.5.  In 5.5, at least I see a wlan0 /dev.  If I
try to configure it with the gui tool or the iw cmd line tools, it does
everything except get an IP address and it times out.

Here are some details:

dmesg:

Any help would be greatly appreciated.
