This is true. I get this output when I boot latest kernel from DENX.
I think I decided I will go to 2.6 because it had the preemptible kernel
option which I will probably need later on.

Root file system on NFS doesn't work though. I get this errors:

But this is not that big of a problem. I'll just boot stand alone images.
So, for writing a driver for my RTC i2c module I should look at
Documentation/i2c/writing-clients right?
And it should be under
[*] I2C Chips support ---> right?
Best regards,
Ivica
