dmesg for AHCI mode is missing.

Here, you are using "combined" mode, and you have a SATA and an IDE
controller.  This does **NOT** mean you have a PATA-SATA bridge anywhere, it
is full SATA, but some drives will look like they are behind a ICH5 PATA
controller for Linux.

You see it as a legacy ide PATA device because of the combined mode, and
because you are NOT using libata to drive the PATA logical interface.

You could also have it as a libata SCSI PATA device, if you ditch the ide
drive in a new enough kernel.

Another SATA drive... on an AHCI (SATA) head now.

As you guessed, if you want to see both as SATA, you do need to get rid of
the compatibility mode.
