this change makes my machine hang completely (even not able to break
into kernel debugger) by the time the interfaces are setup (upon
boot after hostnames gets set from rc scripts).

it's a dual cpu amd64 with a tyan K8SE which has 2 bges onboard:
Broadcom BCM5704 A3, ASIC rev. 0x2003

backing out this one makes it boot again without any problems.
