This patch fixes ram init problems when using the 9W Sempron part.

Trying to read the FIDVID register when the processor does not support FIDVID control causes a GP Fault. This patch reads the startup FID from a different MSR. I have verified this patch to work on the dbm690t platform.

This patch includes the changes I submitted a few days ago that haven't been acked yet. 


I now have a working Coreboot system. ( Although SATA needs a little work so I am not booting linux yet. ) But at least FILO comes up.
