Eyetech had nothing to do with that ...
AFAIK the VIA-ones are the easiest to connect to an "odd" NB, and
thats why Mai choose an rather old VIA-one for the eval-board
which was later replaced with a somewhat newer but pin-compatible
versiojn in the retail version of the mobo (aka A1).
Even the Pegasos use a VIA-SB, only one that was a bit newer and
orginally intended to be used in laptops (thats why there is so
much onboard stuff).
Getting information on how to use these chips (HW&SW) was also
very important.
