Maybe needless to say, but I'd be happy to test (although the IRQ line too 
busy issue may render the results unusable (I've problems with 2 different 
cards on different hardware / notebooks.) Also, I'd rather not annoy the 
developers with an issue 3Com needs to fix, so please say so if I do :-) 

Anyway, if I can help the project, I'd be happy to do so.

I have a
0000:07:00.0 Network controller: 3Com Corporation 3com 3CRWE154G72 [Office 
Connect Wireless LAN Adapter] (rev 01)
inserted in the PCMCIA slot and used via yenta_socket.

The patch JB sent to me two days ago is the same I suppose? It oopsed for me 
frequently when removing either card or driver, I'm not sure what caused 
this, though.

Can I help?

Your conscience never stops you from doing anything.  It just stops you from 
enjoying it.
