I have a debug kernel built..anything I can do in the meantime?
I imagine Pascal will be sleeping right about now.

Thats pretty well the same board as me, except I dont have the 2
mini-pci slots. Mine comes up as
Geode LX: PC Engines ALIX.2 v0.99h tinyBIOS V1.4a (C)1997-2007
Geode LX: PC Engines ALIX.3 v0.99h tinyBIOS V1.4a (C)1997-2007
Perhaps engage the PCEngine's folks to see what the difference is and if
they know what might be up.
