Okay... but when booting using the fb providet by radeonfb I get no
accel (fbset -i tells it is deactivated) . So I patched radeonfb to set
info->fix.accel = FB_ACCEL_ATI_RADEON (similar to the aty-driver). Now
directfb loads its radeon driver but it exits immediately...

This part of the patch I discoverd after I tried my self-made hack seems
to do the same (if not more ;-) ) but it isn't part of radeon_base.c as
it ships with linux-2.6.9
 -      if (noaccel)
 -              info->fix.accel = FB_ACCEL_NONE;
 -      else
 -              info->fix.accel = FB_ACCEL_ATI_RADEON;
 -
 -      fb_alloc_cmap(&info->cmap, 256, 0);
 -
 -      if (noaccel)
 +      if (noaccel) {
 +              info->fix.accel = FB_ACCEL_NONE;
                info->var.accel_flags &= ~FB_ACCELF_TEXT;
 -      else
 +              info->fbops = &radeonfb_noaccel_ops;
 +      } else {
 +              info->fix.accel = FB_ACCEL_ATI_RADEON;
                info->var.accel_flags |= FB_ACCELF_TEXT;
 +              info->fbops = &radeonfb_ops;
 +      }
 +      fb_alloc_cmap(&info->cmap, 256, 0);

Nor the lines that the patch removes are part of the official
radeon_base.c

They should be around line 1750

Ciao,
