Typo, I guess you mean "weirdly".

Yup, obviously correct.

This is more surprising. How did the interrupt type suddenly change
from "falling" to "low"? (Note that I am not an interrupt expert.)

Anyway, thanks for fixing this. This is one of the i2c drivers that I
can't compile on the architectures I work on, so I can't spot the
breakage.

I guess you want this fix in 2.6.18?
