I don't think your CPU is at fault. While I don't have any Crusoes, I 
have several machines, ranging from Pentiums running at 200 MHz to 
Pentium IIIs running at 933 MHz, with AR5212 cards in them. They run 
7.0-, 7.1-, and 7.2-RELEASE. While I do get some "stuck beacon" and 
"device timeout" messages on them, they can all push at least 2 MB/s on 
the AR5212 cards, and I am assuming that your Crusoe is faster than a 
Pentium 200.
