I just removed my hard drive to continue this investigation. In my 2010 (with navigation, STDRD), the drive is still a PATA. The drive info can be found here:

I use linux so I had a little more luck seeing the partition table to see the partition ID's. This is what I saw with fdisk:

The number of cylinders for this disk is set to 9729.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): p

Disk /dev/sdd: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x6ad4b821

   Device Boot      Start         End      Blocks   Id  System

/dev/sdd10           9709        9729      168651   4d  QNX4.x

Command (m for help):
As you can see, the Partition types are QNX, which leads me to believe that the OS may also be QNX. That will require more investigation. The fact that it is Unlix-like is very promising.

For more info on QNX, Google it, I like what I'm reading here:

In linux 2.6.31, the QNX support is still experimental, but I'm not too concerned considering I will never modify the original drive. I am currently dd'ing the drive into an image on my drive and will be getting another drive for hacking soon. If there is anything we can do with this, I'm confident that we will find it. But this is something that requires a lot of care and caution as well.

If anyone else plans to remove their disk in order to hack with this, even though it is QNX, I still recommend that you disconnect the battery before removal. Also, the carriage around the drive is not refined so if you don't handle it with care, the rough edges can slice through your skin.
