Johannes,
In the current wireless-testing (v2.6.26-rc9-14207-ga520bdb), rtl8187 is broken.
In most cases, it is unable to complete a connection. Occasionally, it will
authenticate and even get an IP using DHCP; however, only a few pings get
through to the AP before the connection fails completely.
Using bisection, this problem was traced to:

mac80211: fix TX sequence numbers
This patch makes mac80211 assign proper sequence numbers to
QoS-data frames. It also removes the old sequence number code
because we noticed that only the driver or hardware can assign
sequence numbers to non-QoS-data and especially management
frames in a race-free manner because beacons aren't passed
through mac80211's TX path.
===============================================================
The validity of the bisection was confirmed by reverse application of the patch.
The resulting driver worked.
The appears that rtl8187 needs some kind of modification such as b43, b43legacy,
and rt2x00 got in the original patch. I'll be studying the changes to the other
drivers to see if I can find the problem, but I will appreciate your help when
you get a chance. Perhaps after your trip to Canada is over.
Thanks,
Larry
