A change was recently added to bge (r1.140) to address some issues
with locking in the driver when performing PHY accesses which was 
also causing watchdog timeout errors.  I need to look at those
changes and see if they are applicable to the bce driver as well, 
though I've been having problems loading both bge and bce as
modules on -CURRENT (causes a panic).  If I can get past the module
problem I'll look at the bge change soon.
