Hi, I have a ATI HD2400XT in my notebook and tried the radeon.ko module with modeset=1 (X cannot use this, yet). While this gives me a framebuffer console with 2.6.32, it only shows a blank screen with linux-2.6.32.2.
The output below is with 2.6.32.
Also not that this laptop has not HDMI out, only DVI. No external monitors are
connected.
