Problem w/ SATA/IDE on Kirkwood 88F6281 board:

I've got U-Boot 2011.12 working well on a 8192 Kirkwood board, _except_ for a nagging SATA problem. Currently, it loads and executes U-Boot fine, it boots fine from a USB drive, but I'm unable to get the SATA port to function correctly. Any insight from Albert, Prafulla or anyone else who recognizes this problem, would be greatly appreciated.

It will detect an known-good-SATA-drive with known-good-ext2-partitions and list its specs, but there are some errors:
