Well, finally atacontrol is born (yes it is still infantile).

That means some things has changed, to name a few:

1. The sysctl hw.atamodes does no longer exist.

2. The options ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC, ATA_ENABLE_TAGS
   no longer exists.

3. There are new tunables to set the boot behavior etc, see ata.4

4. Atacontrol can change the transfermodes etc on devices, and allows
   for detach/attach/reinit of ATA/ATAPI devices, for more see atacontrol.8

Let me know of any problems you may encounter...

Enjoy!
