Further information: Removing radeonfb from /etc/modules makes the screen stay at 24 lines resolution, resulting in a visible console output also for kernel 2.6.8. Maybe the framebuffer shoud not be loaded for 2.6.x kernels? Thanks anyway.
Replying to the mail from Francesco P. Lovergine" <[EMAIL PROTECTED]> with cut an paste from the debian-kernel mail-archives (I'm not subscribed, so I missed your reply) Svante Are you using radeonfb (even statically compiled)? radeonfb is loaded but unused: radeonfb 59112 0 Did you try vesa framebuffer? veasfb is loaded but unused: vesafb 6656 0 Are your laptop a SXVGA one or not (i.e. capable of 1400x1050)? Yes. What's the output of fbset after initialization? What is fbset?? Did you try to switch back to console from X? Nothing changes, still a black screen
