8xx: i2c-algo-8xx - fixed timeout detection and transmission errors

Try changing all
  i2c->i2c_i2com |= 0x80;	/* Begin transmission */
to
  i2c->i2c_i2com |= 0x80 | 0x01;	/* Begin transmission */

That should remove the need to do force_reinit(cpm) I hope.
See http://ozlabs.org/pipermail/linuxppc-embedded/2005-August/019600.html for a litte more info.

Also, I think you should remove the busy wait code. Its not needed IMHO.
