ok, one by one.

1) /lib/firmware/radeon

I installed firmware-linux-nonfree (Debian v0.33), added the necessary lines to
the kernel .config to have them all included.

Booting with this (radeon.modeset=0 or =1) was not different or better then
without.

2) PCI Quirks

I added CONFIG_PCI_QUIRKS=y to my .config

This got me some difference:

a) a 30s lag where the firmware should install:

b) Xorg seems to be faster (glxgears shows around 730 FPS now == 15% increase).
Here's the (relevant part of the) log:

Otherwise no (EE) in there and no more (WW) lines.

So, many thanks for this improvement alone (factor 12 against software renderer
only).

How can I address this firmware problem ("Failed to load firmware")? Why is it
the R600_rlc.bin and not the R700_rlc.bin? Is there a newer/better one around?

Anything more I can do or test?

cu, RandomCore
