Subject: Add Siemens SITEMP-G1 board

The code is loosely based on AMD dbm690t (and copied from there)
and adapted to match the Siemens SITEMP-G1 board.
It boots both Linux and Windows XP (and if it doesn't then complain
with me [Patrick] because in that case I must have messed it up when
integrating the patch)
