Yes, do please continue.  I currently have a hackish implementation that 
is used only on
the sandburst boards, as I didn't want to pollute the tree making 
others' images larger.
I added code for the 2nd i2c bus on the ppc440gx, as our boards use the 
2nd bus for
temp sensors/fan control and wanted the fans turned on during boot.  If 
the OS doesn't
load for some reason the board would cook as the fans weren't being 
touched until the
kernel started.

I'm v.interested in how this turns out.
