Dell has been pushing plain Ubuntu for a while I think.

Their 13 XPS laptops are always out of stock in Germany, so I never managed to try them out.

ASUS used to sell 1215B ones with Ubuntu on the German Amazon store, which I managed to get for travel purposes.

But in spite of those two examples, I don't see most OEMs would play ball regarding OEM distributions and updates.
