See patch for details.
I have an ASUS K8V-X SE with the named NB, and this patch is sufficient
to get the HT link working properly, and to get a working V-Link with
the southbridge.
The modifications in the vt8237r directory allow the respective SB to
find the K8T800 and K8M800 NBs.
I will need someone with a K8T890 to test this patch to make sure it
doesn't break anything on the K8T890 side.
