Hi Nobel,

I'm the proud owner of a Dell Latitude D620 and I faced the same problem
like you. Using 6.1 I was able to use the bge-nic but on CURRENT it
panics everytime I try to use it (Set it up or assign an IP-address).

The problem is probably, that the PHY of the be-nic isn't recognised
and a generic PHY attaches (See your dmesg: ukphy0).

Please try the attached patch. It make the Broadom-PHY attach to the
card. For me it works great, although it does not solve the firmware
handshake timeouts.
But please note: I'm no c-programmer and the patch may be crap, but at
least it works ;)
