I am still getting firmware handshake timeouts and/or watchdog 
timeouts.  Most importantly it panics or get witness warnings (lots 
of 'memory modified after free').  Panic goes like this (while 
kldunload if_bge with dhclient enabled):

brgphy0: detached
miibus0: detached
bge0: firmware handshake timed out, found 0x4b657654

As you can see the packet length is really bogus.  I am wondering if 
the chip is actually initialized correctly to begin with.
