[LinuxBIOS] Geode LX support

[Indrek Kruusa]

Could it be that setup for one LX board (amd/norwitch) does something very 
special that prevents this LB ROM to run (to some extent) on another LX board 
(artecgroup/dbe61)? It stops at postcode 0x10 (Entry into protected mode). I 
suppose that whatever LX target rom should be able to reach at least the 
pll_reset() on any another LX board without much problem.

thanks,
Indrek
