I just had a quick look - the rw driver from 2.6.24 to 2.6.30 actually
went through the ieee80211 to mac80211 change.
('git diff v2.6.24:drivers/net/wireless/zd1211rw/
v2.6.30:drivers/net/wireless/zd1211rw/' for those who has
wireless-testing).
I have a bunch of patches which bring the 2.22 vendor driver up to
2.6.29 and 3.0 the vendor driver up to 2.6.30:
http://htl10.users.sourceforge.net/patchsets/
It doesn't fix the rw driver, but might be good enough for you? I
didn't spent any more time on the 2.22 vendor driver after 2.6.29
because 3.0 was released then. The 3.0 vendor driver can be had from:

http://www.kernel.org/pub/linux/kernel/people/mcgrof/zd1211/

It would appear that the rw driver's ieee80211->mac80211 conversion
has broken big- endian platforms, at a first guess.
( I still maintain that
http://marc.info/?l=linux-wireless&m=124906700820860&w=2 is a bit
different from your situation, since the other poster never had the rw
driver working on bigendian platforms). In any case, it might be
interesting to hear from others if recent versions of the rw driver
can be confirmed to work on bigendian platforms.
