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.
