as a clarification, perhaps: thunderbolt, in essence,

"export" the PCI(x) bus to outside the chassis, with safe
hot-plugging.
Firewire Expresscards are basically using one PCIx lane: there are PCIx
cards for desktop computers accepting Expresscards that basically just
put the wires through (and aren't good at hotplugging). They may or may
not also have a USB receptable in order to provide a USB port to the
Expresscard (Expresscards can choose whether to talk via PCIx or USB:
WWAN cards and most card readers use USB, Firewire adapters generally
use PCIx).
So if your statement is correct, I'd speculate on a
"thunderbolt-to-Expresscard" adapter also being just wiring and
consequently not requiring additional driver support. If that were the
case, this could be a way to use an existing Expresscard Firewire
adapter (and thus drivers with some expectation of working) with a
modern laptop.
