289 Basically any adapter using the parallel port as an I2C bus with
290 no extra chipset is supported by this driver, or could be.

316 the clean but heavy parport handling is not an option. The
317 drawback is a reduced portability and the impossibility to
318 dasiy-chain other parallel port devices.
320 Don't say Y here if you said Y or M to i2c-parport. Saying M to
321 both is possible but both modules should not be loaded at the same
