"e.g. making a TI-89 emulator should be ok for the market, but you can't include TI's ROM"

I don't think so. For example, I know the PSX emulator didn't include any of the required BIOS files and they are all still removed.

It seems that if someone big enough complains, Google will remove any emulator.

Well, despite acting pretty similar in the past in a few key cases (I crack my self up :P), TI has usually acted more or less sane when dealing with their hacker community. They have no issue with the numerous emulators out there for their calculators so long as you don't distribute one of their roms.
