I finally have a working pegasos motherboard as well as a working kernel
with a 1.6 radeonfb. I have also installed Daniel Stone's X 4.3.0
debian/sid packages, and notice the following :

  1) radeonfb works fine in 8bpp and 32bpp but depth 15 and 16 only give
  me some very dark grey.

  2) when running X with the UseFBDev option the colors are bad, i guess
  it is an endianess problem. (with and without accel)

You want radeonfb from a recent benh kernel, anything else is more or
less broken.

A, ok, but then, i think i will not worry about this, and simply port
the pegasos changes to the latest benh kernel (or maybe i can simply
replace the radeonfb.c file ? Mmm, i will try it). By recent benh
kernel, you mean the one from the linuxppc_2_4_devel tree or the one from the
linuxppc_2_4 tree ? Or maybe both are the same.

  3) When running X without the UseFBDev option, the colors are good,
  but i get garbage when i return to the console. Not exactly garbage,
  at first it is ok, but when i enter a line or somehow pan the screen,
  the corruption start. Doing a vt switch and back redraws a clean
  screen.

Sounds like the radeon driver doesn't restore the framebuffer aperture
byte swapping correctly.

Yep. same solution as above i guess.

Sound is also messed up, i guess it is also an endianess issue, but most
probably due to endianess issue in the VT82Cxx driver, and no other
powerpc box should use this, i think.

Thanks.

Friendly,
