This is most definitely a driver bug.  It's not setting up correct
symlinks in sysfs.  NM has nothing to do with this really, because NM
depends on drivers reporting themselves to HAL correctly.  HAL will
report the device's type based on sysfs links.

The driver you have is likely not implementing the 'get_wireless_stats'
handler, which in turn means there's no /sys/class/net/ath0/wireless/
directory, which means it's not recognized as a wireless card.

>From airo:

static const struct iw_handler_def	airo_handler_def =
{
	.num_standard	= sizeof(airo_handler)/sizeof(iw_handler),
	.num_private	= sizeof(airo_private_handler)/sizeof(iw_handler),
	.num_private_args = sizeof(airo_private_args)/sizeof(struct iw_priv_args),
	.standard	= airo_handler,
	.private	= airo_private_handler,
	.private_args	= airo_private_args,
	.get_wireless_stats = airo_get_wireless_stats,
};

That last line there is the one you likely care about for the madwifi
driver.  But you must be using an old driver, because AFAIK the new ones
have had the correct bits for quite a while.

Cheers,
Dan
