Ouch !!! Do you by any chance have a worklog of this setup Jason ? I'd be willing to setup and test this myself. BBBlfs is pretty interesting, but I was under the impression this was an Android only thing - As per the GSoC project . . . granted, Android is (sort of ) Linux too . . . I did find the github project page, the instructions seem complete, but I was more interested in knowing what you had for a run script off the udev rule mentioned above.
