On a per-driver basis if the modem has some way of reporting it.  Ie,
for Gobi devices we'd check with QMI for capabilites, for other modems
like the multi-mode Verizon/Sprint devices that do CDMA+HSDPA we'd
either user GCAP or we'd just hardcode it based on the GMM response or
USB IDs.

Not necessarily.

I think we need to keep them separate for now; the modems I'm thinking
of here are ones like the Verizon UMW190 and USB1000 and maybe even
world-mode phones.
