bge auto-negotiation fails with recent current

Yesterday I updated my laptop for the first time since May 10. The 

The bge device does not auto-negotiate. 

After booting to single-user, but device looks fine
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active

As soon as I do 'ifconfig bge0 up', the link goes down and I see:
media: Ethernet autoselect (none)
status: no carrier

If I manually set the media to 100baseTX, it comes up. If I set it back
to autoselect, it again reports "media: Ethernet autoselect (none)" and
"Status: no carrier".

The device probes as:
bge0: <Broadcom NetXtreme Gigabit Ethernet Controller, ASIC rev. 0x4101> mem 0xb0200000-0xb020ffff irq 11 at device 0.0 on pci2
miibus0: <MII bus> on bge0
brgphy0: <BCM5750 10/100/1000baseTX PHY> PHY 1 on miibus0
brgphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseTX-FDX, auto
bge0: Ethernet address: 00:01:6c:e9:8f:51
bge0: [ITHREAD]

There have been several updates to if_bge.c since May 10, so I'd appreciate
suggestions as to what might be a good place to roll back to. If I don't
get suggestions, I'll do a binary search, but I hope to avoid that.

Any idea what might be going on?

Let me know what details I can provide.
