Hmm... seems I spoke a little too soon. Bugger refuses to 'ifup' now with
WEP, started getting those pesky "requeueing command 0x0016 due to timeout"
followed shortly thereafter by a kernel oops. There must be some kind of
race condition somewhere, or something going rotten in the firmware, since
the more I play with it the more obstinate the thing becomes. Once it DOES
associate and dhcpd does its thing, it's rock solid. A little thirsty on the
power consumption side but the link stays up...
