That sucks. Sadly, it was the fashion for vendors to offer only the
compatibility mode of operation for a while.
You could try "lsmod | egrep 'ahci|piix'" and see what the output is.
If both are present, and both are in active use life is harder, but just
one present would be a start.

Well, I have no idea, I fear.

*nod* Also, the "operating mode" is probably not going to be listed, so
even "ICH7 SATA" doesn't tell you everything you need to know.

*nod* Well, you /could/ test it: drop to single user mode, remount
critical filesystems read-only, sync, and pull the device.
Then look for error messages. ;)
