Well, I am kind of income-less right now, can not afford new expenses.
BTW, here is the dmesg and lsmod output from Arch (open-soure driver
but I guess with binary-blob in kernel), gNewSense (totally free and
works great with radeon) and PARABOLA (free like gNewSense but booting
and X issues). Boh gNewSense and Arch dmesg outputs have one common
lin:

   fb0: radeondrmfb frame buffer device

 PARABOLA does not have this. I think this is what causing the X
failure. Any idea why PARABOLA does not have it when gNewSense has ?
