Maybe instead of maintaining a table in the Wiki, more information could be
printed to the console/log files by the Radeon driver(?)? This would of course
not help users wanting to easily know if a Linux kernel upgrade would bring
them new supported features. They can only look at the source comments/print
outs in the repository.

So Alex, how hard would it be to print something like the following to
`Xorg.log` or the kernel ring buffer?

    Powermanagement: pre-R6xx does not support low power states: disabled
    Overclocking: not implemented yet, using default
    Temperature reading not working correctly yet.
