Attached patch fine-tunes the V-link bus between K8T890 and VT8237R and set it 
to 8X transfer rate (up to 1066 MB/s) similar code placed here would be needed 
for VT8237A/S etc. Using VIA recommended values despite they are for K8T890CF, 
this is K8T890CE (still dont know what is exactly different).

This patch enables the parity error reporting on V-Link, so it enables NMI 
generation for the SERR# errors. The NMI may not be generated, maybe port 61h
needs some tuning too.
