It causes some initialization issues to happen. I get the following
messages on every boot:
i2c-sh_mobile i2c-sh_mobile.0: Transfer request timed out
i2c-sh_mobile i2c-sh_mobile.0: Polling timed out
three times in a row (there's a delay too).
The A4R patch is the source of that.

Yes, it does, AFAICT.
