damien 628178d704 o Clear device-specific PCI register 0x41 (Retry Timeout) during attach 
and on resume (reported to fix issues with ACPI)
o Add monitor mode support
o Add WPA (802.11i) support (not tested extensively though!)
o Add a device specific sysctl to control the tx antenna (default to
  antenna diversity)
o Fix sensitivity setting
o Fix setting of the capinfo field when associating
o Temporarly disable 802.11a channels scanning that was causing firmware
  panics with 2915ABG adapters until I find a better fix.  This breaks
  802.11a support.
o Temporarly switch back to software WEP until I implement hardware
  encryption for AES and TKIP too.
