Unfortunately in the MythTV system I want it for has an old PCI/PCMCIA adapter that only accepts 16-bit PCMCIA cards, so this 32-bit one won't fit.
Below is some info that my help you debug your configuration:
It uses the ath_pci kernel module.
$ lsmod|grep -i ath
ath_pci 97184 0
ath_rate_sample 15616 1 ath_pci
wlan 204764 4 wlan_scan_sta,ath_pci,ath_rate_sample
ath_hal 192080 3 ath_pci,ath_rate_sample
