It's on my todo list, but I'm not sure when I'll get to it. The i2c bus handling in the driver would need to be changed. Rather than adding i2c buses as needed, the plan would be to walk the i2c gpio table and add all the potential buses then point users of those buses (connectors, thermal chip drivers, etc.) back to the bus they need.

Just for the record I ran lm-sensors and it found the temps and such for my 5770.
here is the output that I get:
radeon-pci-0100
Adapter: PCI adapter
temp1: +56.0?C
The sensors-detect script did a good job probing my card and finding every little i2c bus and fingering it. The thing found this as a 'battery sensor' or something like that.
Weird, but it appears to work.

r6xx and newer radeons (like your 5770) have an internal thermal sensor that is exposed by the driver on most cards that utilize it so there's no need to probe for it. On pre-r6xx hardware, the thermal sensor was an external i2c chip, so you need to load the appropriate i2c hwmon driver.
