I have a 5700 ( no idea if that's  a B or not ) and a 5703:

bge0 at pci2 dev 2 function 0: SysKonnect SK-9Dx1 Gigabit Ethernet
bge0: interrupting at irq 52
bge0: ASIC BCM5700 Altima (0x7104), Ethernet address xx:xx:xx:xx:xx:xx
brgphy0 at bge0 phy 1: BCM5411 1000BASE-T media interface, rev. 1

bge0 at pci0 dev 3 function 0: Broadcom BCM5703 Gigabit Ethernet
bge0: interrupting at ivec 371c
bge0: ASIC BCM5702/5703 A2 (0x1002), Ethernet address xx:xx:xx:xx:xx:xx
brgphy0 at bge0 phy 1: BCM5703 1000BASE-T media interface, rev. 2

the latter works alright, the former has a different problem - it will  
work fine for a while and then get stuck, apparently not receiving  
anything. Any ideas what to look for?

have fun
Michael
