SIOCSIFFLAGS: Name not unique on network with b43

Hi all,
I'm on Kubuntu 2.6.32-rc8-wl and according to lspci I have this Broadcom card:
Broadcom Corporation BCM4312 802.11a/b/g (rev 02)
and modinfo b43:

My problem is that I would use multiple interfaces (as mentioned here
http://wireless.kernel.org/en/users/Drivers/b43#features ) using one
for AP and one for station but I always get this error while trying to
up the other interface:
SIOCSIFFLAGS: Name not unique on network

This is the command list that I've done:

service network-manager stop
iw phy phy0 interface add wlan1 type station (or managed)
ifconfig wlan1 up

then I used wpa_supplicant on wlan1 and all ok. But when I try to up
wlan0 that from iwconfig shows this:
wlan0     Link encap:Ethernet  HWaddr 00:1a:73:xx:xx:xx
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

or when I try to use hostapd:
Configuration file: /etc/hostapd/hostapd.conf
ctrl_interface_group=0
ioctl[SIOCSIFFLAGS]: Name not unique on network
nl80211 driver initialization failed.
wlan0: Unable to setup interface.
rmdir[ctrl_interface]: No such file or directory
ELOOP: remaining socket: sock=5 eloop_data=0x80f0a38 user_data=(nil)
handler=0x80874

so how to have multiple interfaces (in my case one AP and one station) with b43?
I haven't found a solution googling

Best Regards
