[Bug 575296] Re: Ubuntu boot delay - nForce error

[ingo]

I digged further into this issue and found some difference in i2c-
modules between Hardy and Lucid:

Hardy:

kern.log says all ok:

Worth to mention:
in Hardy module i2c_nforce2 depends on i2c-core module, not so in Lucid.
Actually module i2c-core does not exist in Lucid!
