I have posted a snippet previously — you basically search for
"firmware=..." in kernel modules. It's doesn't always work, though —
e.g., it won't with DVB firmware, I think.

iwlwifi is somewhat special, with its multiple versions and
subversions. In this case, 6000{,g2{a,b}} are different cards, and
-[456] are different firmware APIs, with multiple APIs supported by a
given kernel. See, e.g.,
/usr/src/linux/drivers/net/wireless/iwlwifi/iwl-6000.c.
