No difference in -current.  After looking at the output of pciconf a little 
closer, I noticed that the standard IDE controller has the device ID you 
mentioned and it is recognized properly.

The SATA controller has a device ID of 0x00e510de.  My amateur hackery 
(consisting of adding entries to ata-pci.h and ata-chipset.c) yielded a 
nicer-looking identification of the controller at startup, but the drive is 
still being accessed using UDMA33.

Anyway, thanks for the help.  I'll keep my eyes open and play with it as I 
have time.
