hmmm...   I dont think I am up to modifying my kernel source by hand just yet (if I read Ben's response correctly).  Thanks for the solution though.  It's good to know a solution is out there.

While fixing that, I also found & fixed a couple of other corner cases. This fixes booting with a pbbuttons version that scans the i2c bus for an LMU controller among others. Tested on a dual G5 with thermal control (which has heavy i2c activity) with no problem so far.
