Broadcom NIC and Xen problems

I own a Broadcom 440x network card, provided by my Dell Inspiron 6400 laptop. Drivers and Downloads
I use Xen, but I can not create a working network when I use Xen. I can not connect to Internet, I have to delete the software xenbr (a xen bridge) and then I can use Internet but Virtual machines are complety isotated by network.
When this problem will be fixed? I am waiting since version 10.3 of OpenSuse.
