Oh, BTW... there's really no reason to reuse the "lm63" name when both
chips are not fully compatible. Please introduce a new name for the new
chip. It's fairly easy.

I've added detection support to sensors-detect:
http://dl.lm-sensors.org/lm-sensors/files/sensors-detect

I would appreciate if you could try it and report.

I would also appreciate if you could provide a dump of your chip's
registers (using the i2c-dev driver with i2cdump - part of the
i2c-tools package) for my collection.
