Please send (I forget) the hardware info (lspci) and the register values
from ethtool -d ethX.

Some part of the power control doesn't work on Rene's system, so
device falls off the bus. Probably no auxilary +5 supplied, the register
values will tell whether driver is at fault (turning on aux when not
available), or hardware is lying about vaux.
