My card doesn't work with ath5k, i've tested module from 2.6.25 and now

It's a PCMCIA card.
Vendor: TP-Link TL-WN610G

I cannot see any networks during scanning (iwlist).

ifconfig wlan0 up (works after ~5 tries)
iwlist wlan0 scan
shows no networks (no problem with madwifi)
During iwlist scan log is flooded with:

Same log messages if trying wpa_supplicant

Providing further packages for madwifi seems difficult with >=2.6.26, or see
you any chance?
Should i file a bugreport (arch or madwifi or LKML)?

Searching a little with "ath5k_chan_set: unable to reset channel" i saw more
users which maybe similar problems, ex.
http://madwifi.org/ticket/808 (Little confusing...)
and this in our forum could be similar:
