Currently I cannot check your changes in LB because the TC320 is a "production 
system". It works as my main fileserver...

Yes, NIC is on board. But 0e.0 is the correct one. I'm not sure why my system 
works with this setting...

Yes.

Ups, both COMs are present at the backplane. So both should be on.

Don't know how to check the GPIO feature.

No superiotool, no check... ;.)

Yes. 2mm 2.5" 44 pin connector. Audio also, but works only with an SMI polling 
driver. Is someone interested in testing my new shiny SMI polling Audio on 
GX1 (currently audio out only)?

Mostly done.
