Ok; this is because d80211 (at least as included in rt2x00 driver) isn't
setting the wireless stats handler, which I believe makes the device
show up in /proc/net/wireless.

See airo, for example:

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,

The ieee80211/ieee80211_ioctl.c file in the rt2x00 driver doesn't set
the ".get_wireless_stats" handler:

const struct iw_handler_def ieee80211_iw_handler_def =
	.num_standard	= sizeof(ieee80211_handler) / sizeof(iw_handler),
	.num_private	= sizeof(ieee80211_private_handler) /
	.num_private_args = sizeof(ieee80211_ioctl_priv) /
			    sizeof(struct iw_priv_args),
	.standard	= (iw_handler *) ieee80211_handler,
	.private	= (iw_handler *) ieee80211_private_handler,
	.private_args	= (struct iw_priv_args *) ieee80211_ioctl_priv,

Jiri, what's involved here?  The actual handler for get_wireless_stats
is quite simple; see below.  It returns a 'struct iw_statistics' for
which it looks like all the information is available in d80211

static struct iw_statistics *airo_get_wireless_stats(struct net_device *dev)
	struct airo_info *local =  dev->priv;


	return &local->wstats;
