Well, you can't load modules unless you're root.
The assumption is that all troublesome systems have a
PIIX4. i2c-piix4 won't load if it's an IBM.
If a) the problem is something not on a piix4 bus,
and b) the user compiled-in those modules or loaded the modules
before, then there could be a problem.
