A similar offer here.
I'm running a couple of AVR slaves, a temperature sensor
and a ferroelectric RAM off I2C on an AT91R40008.
Repair the address in sig in the obvious way - sorry
for the bot-mess.

Create your own I2C interface using two I/O port lines. I can give you some
source code if you want.

I was looking at the Atmel AT91R40008 for a new design. However I
realised it dosen't support I2C.
Does anyone have a recommendation about how to interface a real time
clock, and maybe a serial eeprom. Is an I2C bus master a sensible
approach, perhaps from Philips?
The main objectives are low cost and good availbility.
regards,
Johnny.
