After a bunch of googling, I happened on a thread that mentioned "modinfo"
With that, I can at least get a listing of options for the modules. Unfortunately, it does not explain what the options do.
For example

$ modinfo cx88_alsa
filename:       /lib/modules/2.6.32-22-generic/kernel/drivers/media/video/cx88/cx88-alsa.ko

parm:           enable:Enable cx88x soundcard. default enabled. (array of bool)
parm:           index:Index value for cx88x capture interface(s). (array of int)
parm:           debug:enable debug messages (int)

index: Index value for cx88x capture interface(s). (array of int)
tells me I can set index to an array of ints, and that they are index values for cx88x capture interface(s),
but I have no idea what an index value for cx88x capture interface(s) are.

Where can I find out?
