dual wifi, one as access point

[vigor]

Did anybody bringing both network interfaces, one in access point mode ? How does it work for you ?  
I am concerned that both interfaces have same MAC address 34:c3:d2:7a:ba:77, and adding hwaddress in /etc/network/interfaces
does not change that. so my wlan0 connects to my home wifi router, that part works, but if i do that the access point on wlan0 does not work, clients can't connect to it
