This is on HSI bus. I am running ofono on the N900 (not tethering).

From what I understand, I am loading all of the necessary drivers for
this to work (nokia-modem, which pulls in its dependencies
automaticall). 
As I stated in my original note, before moving 'legacy
device' initialization to udevng, ofono would at least 'see' the
modem. The test script 'list-modems' would list it, now it does not
list anything.
