Hi,
AFAIK the ALIX1.C can be considered supported in v2 now, but we don't have a status table for what exactly works or doesn't work yet, so I added one:
http://linuxbios.org/PC_Engines_ALIX1.C_Build_Tutorial
Please fill out the table after testing the hardware with the current svn code.
I marked the board as "OK" in the wiki (list of supported boards) for now.
Thanks, Uwe.
