Seb,

If you give up, you can just use the PPC I2C routines I wrote for my
book.

http://www.embeddedlinuxinterfacing.com/chapters/10/SAA1064_rpxcllf.c

I think you can just change the I2C signaling macros for your hardware
and get things running.

I used this code just yesterday for an x86 SBC talking to a DalSemi
digipot.
