The chip claims to comply to the AHCI standard so, much like a previous poster, I added the PCI ID of the controller into the AHCI driver, compiled the 2.6.14 kernel and crossed my fingers. I met with the same problems as were found earlier. I am fairly certain this is an issue with the kernel driver and the new VT8251 chipset. As far as I can tell this is the first board the chip is shipping in and the board has only been on the market for about a month at this stage. I am presently unsure how to proceed in order to diagnose or address this problem. My experience with kernel hacking is pretty limited but I would be willing to help out by testing whatever I can and I am happy to do some legwork and research to get this going. Would anyone be interested in helping me address this problem? I have attached the relevant portions of kernel messages below.
