SUNGEM config

On Debian systems, this is done by a small daemon named ifd in the
laptop-net package.

Unfortunately, it uses the SIOCGMIIPHY and SIOCGMIIREG ioctls for link
detection, which on my Pismo reproducibly lead to machine check
oopses.  I've managed to track down the problem, a patch is included
below.  Basically, instead of really reading the registers it fakes
and returns a register setting from the cached status of the device.
Right now, it is fairly ugly, since it only works for that relevant
one bit.

Regards, Jens.
