Just curious:
- 3 are in regular connectors
- 1 each in the mini PCIe slots
...but hardware readouts indicate 8 USB 2.0 ports. Where are the other 3?

No, that's not it. The docking station has a hub.
My count:
* 3 external ports
* miniPCIe (probably only the WWAN slot)
* Bluetooth
* Fingerprint reader
* SD Card reader
* 1 port to docking station hub
That is 8 by my count.

The X61's SD card reader is a PCI device, not USB.
Otherwise, your count is correct.

After checking the schematics, the 8 available USB ports go to:
Bluetooth
WWAN
Cardbus Controller (not sure why, but there it is. The controller chip is a Ricoh R5C847. Maybe it performs some other tasks as well?)
Fingerprint
USB ports * 3
Dock

Looks like you are right:

It mentions that it can function as a USB-based ExpressCard controller. It probably allows an ExpressCard passive adapter to function.
So mystery is solved.

I always assumed the SD slot was over USB like I've seen it on other systems I owned. Otherwise, I would be able to boot off it
Oh well, mystery solved.
