Hi,

when I started an i386 server with a NetBSD 4 RC2 kernel[1], I hit what 
seems to be a regression in the bge(4) driver. A NetBSD 4 beta 2 kernel 
from 2007-08-27 works fine.

-- any ideas? I see quite a lot of bge related pullups in doc/CHANGES-4, 
unfortunately CHANGES* does not have time stamps for the changes. Should 
I send-pr?
