I've discovered something new (on another laptop):
By installing these drivers on my non-multi-finger-capable laptop, I've obtained multi-finger support:
http://www.engadget.com/2010/03/19/synaptics-driver-enables-multitouch-gestures-on-older-trackpads/
I had initially thought it had upgraded my touchpad firmware... but when I booted Linux again, it went right back to single-finger-only.
It seems the Windows drivers must be doing some runtime-only patching of the device firmware.
Now, we just need to figure out how to do the same thing in Linux.

Anyway, this means that the Windows drivers showing real multi-finger do
not necessarily mean the touchpad firmware originally supports multi-
finger detection.
