Atheros wireless problems.

So I obtained a D-Link DWL-AG660 cardbus card, which has a 5213 (I
believe) Atheros chipset in it; it's an a/b/g card.  This is to use
while the chipset embedded in my laptop isn't supported.  It came today,
I installed it tonight and, well, problems.

I can get it to associate and, sometimes, even to get an IP address, but
as soon as I start trying to actually pass traffic on it, all hell
breaks loose.  It starts timing out and the ath_hal starts complaining.

Essential information:

ath0 at pci0:57:0:0:       class=0x020000 card=0x3a631186 chip=0x0013168c rev=0x01 hdr=0x00
    vendor     = 'Atheros Communications Inc.'
    device     = 'AR5212, AR5213 802.11a/b/g Wireless Adapter'
    class      = network
    subclass   = ethernet

>From the dmesg:
ath0: <Atheros 5212> mem 0xf2110000-0xf211ffff irq 17 at device 0.0 on cardbus0
ath0: [ITHREAD]
ath0: WARNING: using obsoleted if_watchdog interface
ath0: mac 5.9 phy 4.3 radio 3.6
wlan0: Ethernet address: 00:13:46:11:6b:41

Then from /var/log/messages:
Sep 24 21:14:11  kernel: ath0: device timeout
Sep 24 21:14:11  kernel: ath0: ath_reset: unable to reset hardware; hal status 3230480741

I've also seen:
Sep 24 21:03:55 auton kernel: ath0: unable to reset hardware; hal status 3310983360
Sep 24 21:02:35 auton kernel: ath0: unable to reset hardware; hal status 0

But it has only been those messages.  I haven't yet tried turning on
bootverbose but I can if you would like.

Any ideas?  Any suggestions?  As I sit here (using the wired em0 instead
of ath0) the lights on the card are happily blinking but it's not doing
anything at all.
