I can give you C code for a Silabs 8051 driving an I2C RTC in bit-banging mode (works with ANY chip)

That part looks like it will do the job, thanks very much Eric.
On the I2C driver, I ported the NXP I2C library from 8051 to NXP ARM a  
very long time ago, it was quite a bit of work to make it work properly. Lot's  
of bugs I had to fix.. and could only do that with a Philips I2C analyzer.
Not something I would want to do again..
