There is an output for the same drive model and firmware release in the 
smartmontools-database list.
http://sourceforge.net/mailarchive/forum.php?forum_name=smartmontools-database&viewmonth=200902&viewday=4

The drive features reported there are very different, e.g:

Worked.

The driver of the SATA controller probably does not support ATA 
pass-through and modifies the IDENTIFY sector to limit the reported 
features accordingly.

Such an issue was already reported for the ITE8212 controller on Linux:
