HD4200M works

[Mathias Picker]

Just a success report for the wiki. 

I have an Acer 5553g with Mobile Phenom and ATI 4200/5000M graphics.
The 5000 didn't work when I tried it last (around RC1), if I remember
correctly it couldn't get at the monitor. It would be way too hot
anyway...

The HD4200M works fine.

This is the pciconf output:

I can switch the 5000M off with acpi_call. Still, the laptop runs about
5° hotter then with 9.2.

Oh, two small problems:
- I cannot use a screensaver with power save, it will not come alive
again...
- I can only switch off the HD5000 after X started. If I do it before, X
just does not start :(


One question: is there a way to stop the HD5000 drm code to load?




Thanks you all for the hard work,
