The I2C driver doesn't work properly with the microcode patch - it
initializes tbptr and rbptr to 0, not r_tbase and r_rbase, and it uses
the INIT_TRX command (which the patched code doesn't support) instead of
separate INIT_RX and INIT_TX.
You might want to try the attached minor patch, which works for us.
