I submitted a bug to the kernel bugzilla, but maybe this is a better place, honestly I don't know how maintained this project is:
The relevant bits are that the card drops the connection randomly, it's not an AP problem, it works fine with the driver from svn (your svn).
WEP keys doesn't work in the kernel, only with svn (tried a few weeks ago with .25 to be honest, not today).
Multicast is missing! I can't use avahi and it's zeroconf magic.
Feel free to ask me for more info, you can check the kernel report for more details, but the summary is basically all.
Thanks for making my laptop have wireless working :)
