@nine:
I experience the same problem. Due to the missing Gigabit-interface, linux starts renumbering the devices and so even via doesn't work any more.

Later linux versions connect to the MAC of the ethernet, which should be better, but it isnt:
My PEG delivers an unknown but reasonable MAC for the Gigabit on first boot. ( Maybe the optional second Gigabit expansion ?)

Like you, I switch the power completely off during night, which might be the cause that some people never experience our problems.

The firmware links sounds interessting, but is the complete sourcecode for a PEG downloadable ?
I don't want to develop a bios from scratch .. I just want to do some minor tweaks ... because waiting for the next OF starts to suck
