I am on x86_64 and I am on a similar situation - I am using the
rawhide kernels from:
http://koji.fedoraproject.org/koji/packageinfo?packageID=8
and the last one that worked for me is kernel-2.6.25.11-92.fc9 - something in
kernel-2.6.25.11-93.fc9 broke connectivity. Apparently the difference
is this set of changes:
http://marc.info/?l=linux-wireless&m=121606436000705&w=2

I just don't feel like mentioning it earlier because I had mistakenly
complained about Herton's
last patch and I don't want to make the same mistake - and I did test
it. Beside Herton's
 ANAPARAM*_OFF patch (which I don't think is the source of the
problem), there is
only one other "rtl8187: Fixed section mismatch in rtl8187_dev.c"
change - but that's is also
obviously right, and besides, its nature shouldn't affect association
anyway; but there is
a lot of mac80211 changes elsewhere, and I wonder.

My symptom is that I can authenticate and associate (apparently,
according to dmesg)
but cannot get an ip address via dhcp. I have tried and just alternate
between the two kernels,
identical steps, etc and one works and the other doesn't.
