That's unfortunate. Then again, the M2V is difficult to get, so it
probably is not a viable candidate.

That would be great! We will need support for newer VIA chipsets anyway,
so if you're 2 months ahead with requests, supporting the K8T890CF and
K8T890CE+Unichrome should be attainable until May 2008.

Good to know that they cooperate.

My list mentioned boards available from German online stores, so it
would be mostly equivalent to "buy now" at ebay.
By the way, the MSI K9VGM-V is available in the US from Newegg for $35.
MSI have been cooperative in the past when trying to port their boards,
so this may be a good choice.
