I should have written Intel 5000/631x/632x/3100 as they are used
together:

Actually i have no idea if i'll have any luck getting something done one
that Platform, but i have two of these Boards, Documentation from Intel
seems to be available, so it's worth a try.

(Real reason is that i've seen the great Presentation from Peter Stuge
at the 25. Chaos Communication Congress (25C3). As i have no boards here
which are supported by coreboot now, only chance to play is trying to add
support for the boards i have. ;) )

Thanks for that hint, will look into that code :)
