OpenHAL has evolved to what is now ath5k, a kernel driver for Atheros
devices.  Historic OpenHAL is not maintained.

MadWifi uses FreeBSD HAL developed by Errno Consulting.  It was a
non-free binary blob in the past, but it was open sourced later.

As far as I know, every channel has a width that cannot be changed.  The
width can be examined by the "wlanconfig" command.
