Actually it was mac80211. In ieee80211_ioctl.c the allowed frequencies for Japan are defined this way:
1574 static const struct ieee80211_channel_range ieee80211_mkk_channels[] = {
1575 { 2412, 2472, 20, 6 } /* IEEE 802.11b/g, channels 1..13 */,
1576 { 5170, 5240, 20, 6 } /* IEEE 802.11a, channels 34..48 */,
1577 { 5260, 5320, 20, 6 } /* IEEE 802.11a, channels 52..64 */,
1578 { 0 }
1579 };
This prevents channel 14 from being used. Changing line 1575 to
1575 { 2412, 2484, 20, 6 } /* IEEE 802.11b/g, channels 1..13 */,
did the trick.
BTW: ieee80211_ioctl_set_regulatory_domain changes conf->regulatory_domain, but this seems not to change the selected frequency table (that one is selected solely based on the module parameter "ieee80211_regdom". Why are there two places to store the regdomain (that seem to be used from different places)?
