The problem with compiling such a list is acquiring the equipment to test.
Most of us just buy a couple APs and live with with we get.

I discovered that the Linksys didn't honor 
Session-Timeouts when I captured it screwing up 
EAP-POTP sessions in progress, despite our RADIUS 
server providing Session-Timeout values in every EAP exchange.
I think it's actually not properly implementing 
the 802.1x state machine in it's timeout behavior.

And I didn't go looking for this.  It was brought 
to my attention when someone else had a problem.

The only AP that I know that works for everything 
I throw at it, during development, is the Cisco 
Aironet 1200 series.   The only problem is that 
it's not cheap.  But it works for me, so I don't try others.
