so I finally booted Linux on my h6315 and it works. The only disappointment is that I bought the wrong MMC card (MMC v4) which is not yet supported (I somehow got the card recognized but only the partition table can be read - after that it hangs). I still have the NFS option for getting my rootfs mounted but somehow I don't like this. Anyway the guys on #h63xx-port told me today that Bluetooth is working and WiFi is almost working.
Maybe I just have to buy another MMC card :-(
