Each driver will try to grab every address it knows about, and will
succeed if the device at that address meets some conditions (which of
course depend of the devices the driver is supposed to handle). So, if
the lm90 driver isn't loaded, the device at 0x4c is free, and the
adm1021 driver will try to get all three devices (0x18, 0x4c and 0x4e)
unless you explicitely prevent it to do so. In your case, and if you are
willing to try that, I would prevent it to access the devices at 0x18
and 0x4e, and would let it handle the device at 0x4c. I think it will
work (although you'll miss some features from the lm90 driver, such as
critical temperatures, hysteresis and extra accuracy). That said, and as
I know your system... backup first ;)

Thanks. I hope your daughter had a good time for the tournament :)
