Just looking them over, they seem pretty reasonable to me.

It would be useful to have some sort of API to get the serial numbers
from the devices.  If I add another device to the one-wire bus, who
knows where it will end up in the list?  If I had the serial numbers,
I could keep track of them.  Being able to force a bus rescan would be
cool as well (it didn't seem like that was possible, but maybe I'm wrong).

Mind you, these are just ideas that I think would be useful ... I don't
view them as prereqs for committing this code.  I think it's okay to commit
now.
