ATH driver doesn't associate with turbo.

thinkpad t40p current as of 6 jan (real current has fatal ata crashes)
    ath0: <Atheros 5211> mem 0xc0210000-0xc021ffff irq 11 at device 2.0 on pci2
    ath0: mac 4.2 phy 3.0 5ghz radio 1.7 2ghz radio 2.3
    ath0: 11a rates: 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps
    ath0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
    ath0: 802.11 address: 00:05:4e:41:ee:cd
nokia ap with orinoco gold card on chan 11
netgear he102 802.11a ap on chan 52 (5.26GHz)

all on same ssid

sometimes ath0 associates with one ap, sometimes the other, and it
will switch from 11a to 11b and not come back to 11a.  e.g., right
now it says

    # ifconfig ath0
    ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	    inet netmask 0xffffff00 broadcast
	    ether 00:05:4e:41:ee:cd
	    media: IEEE 802.11 Wireless Ethernet autoselect (DS/11Mbps)
	    status: associated
	    ssid rgnet-home 1:rgnet-home
	    channel 11 authmode OPEN powersavemode OFF powersavesleep 100
	    wepmode OFF weptxkey 1
	    wepkey 1:104-bit

i suspect the ath driver, as i do not see similar issues in winxp.
but of course, when debugging, i am not sure of anything.
