This seems to show a problem with the CD driver, not the graphics
driver.  I've seen at least one similar report.

The kernel only supports the video parameter for built-in framebuffer
drivers, and the initramfs scripts try to emulate this for modules.  As
you can see, it doesn't work perfectly and this feature is about to be
removed.  You can set the module parameter explicitly in the modprobe
configuration (options radeonfb mode_option=...).  However, radeonfb
will soon be obsolete as the radeon DRI driver supports KMS now.
