I want to enable MIDI in my knoppix liveCD, so I compiled some modules for my kernel.

Problem is I can't install them with modprobe because the /lib/modules directory is readonly, and I can't install them with insmod because apparently they have to be installed in a definite order so that there will be no missing dependancies.

Is there a way for me to work backwards when I get unmet depandancies?

i.e. how can I find what module contains the symbols required by the module I unsucessfully tried to inmod? Grep *.o doesnt seem to do it...

Not sure if this is what you were looking for, but here is how to find all of your modules...
First off, *.o isn't only extension, so is *.ko

So try this.....

find /lib/modules/"KERNEL VERSION" -type -f -iname '*.o' -or -iname '*.ko'

....and it should list all of them.

Hope this was helpful,
