So... no idea if anyone is interested or has some insight, but I would be open to paying/donating to someone who could figure out why there is a difference in how custom and stock ROMs deal with Airaves and how to "fix" it (I use the term fix loosely because it's just a display issue).
Thanks! PM to discuss if you like! I love MightyROM, the signal thing is just irking the bageezus out of me.
