Hmm, a workaround would be a custom init script. Copy the following code
into a new file in /etc/init.d (let's say /etc/init.d/broadcom-fix):

#!/sbin/runscript
description="Reload broadcom and tg3 modules to work around kernel bug"
depend() {
        before net
	after modules
}
start()
{
	ebegin "Reloading broadcom and tg3 modules"
	modprobe -r broadcom tg3 &&
	modprobe broadcom &&
	modprobe tg3
	eend $? "Failed to reload modules"
}

Make it executable (chmod 755) and add it to the default run level
(rc-update add broadcom-fix default).

Better try to start it manually before rebooting so you can be sure it
works as expected.

Hope this helps,
