Sorry for my english.
With pclinuxos-phoenix-mini-2010.11.iso in my usbkey the wireless card atheros 5100+ is recognized as ath0 and dont work, but with
pclinuxos-phoenix-xfce-2010.10.iso this wireless card is recognized as wlan0 and work ok.
I think it is a problem of the last pclinuxos-phoenix-mini-2010.11.iso
