I updated my RELENG_6 system to the tip and tried the same ssh 
command which you mentioned also failed on your system.  I couldn't
duplicate the problem at all.  Are you sure you are actually using 
the new code?  My system is reporting a different driver version
than yours (mine = 0.9.6, yours = 0.9.5):

bce0: <Broadcom NetXtreme II BCM5708 1000Base-T (B2), v0.9.6> mem
0xdc000000-0xddffffff irq 16 at device 0.0 on pci2
bce0: ASIC ID 0x57081020; Revision (B2); PCI-X 64-bit 133MHz
bce0: Ethernet address: 00:10:18:15:f6:96

Are you still having a problem?  Can you change the version number in
if_bce.c (bce_driver_version) and make sure the right driver is loading?
