I just fell in the middle of this thread and don't exactly know what it's
all about. but I do have a Geode base board available. So here is my
info. Please contact me if you want to know more !
Greetings,

PS: anyone else seeing screen corruption in console/text mode with these
boards ? (some chracters from before a screen update stay on the screen).
board:
------
Axiom Technology, SBC84510VEE, 3.5" Capa board, 300 MHz Geode
kernel:
-------
standard RH 7.3 update (2.4.18-5)
