Unfortunately, this doesn't tell me much. :(

*sigh* Look, you told me you tried the card with both 11b and 11g
modes. Which one where you using when the system crashed? It's a
simple question. You could also tell me what access point you were
connected to at the time.

You were not using 11g mode then, correct? (I.e. this was at 11Mbps,
not 54Mbps.)

For PCI or cardbus, it's really simple: just do pciconf -lv and send
it to me.

Unfortunately, I usually need more time than this, and matching
up my free time with your free time is hard.

I just received an SMC card to experiment with, so I'll probably be
busy with that for a while.
