You were right; partly. It was tehre, but I guess the pathes in the kernel
build got mixed up. Since I didn't know which firmware to include I included
all, whihc made the string constant too long and the make fell back to
configuration. So I changed the _DIR to "/lib/firmware/radeon" and added the
firmwares without "radeon/" as prefix. Well, seems to have messed up the build
process.

Anyway, I did a mrproper and just included the R*.bin files. Here's the
outcome:

 $ dmesg|grep drm

I guess a failing ring-test is not that good. Performance (glxgears) is still
around 730 FPS.

Which firmwares shall I include for my HD4290 / RS880?

Shall I disable the VESA console fb device?

Oh, and there was no 30s pause anymore.
