--- Comment #33 from Holger Lenz holger.lenz@onlinehome.de 2010-12-15 20:55:33 --- YES! I can confirm the fix. I have the radeon+r600 driver working in AGP mode stable now. The remaining issues I have been seeing are related to loading the driver: If I do the following procedure, then radeon/r600 works no matter what I do to memory holes or AGP speeds: - Boot to runlevel 3 (ugly 4 char fbcon) - log in as root - modprobe radeon (get nice 132 char fbcon) - init 5 - enjoy X in native resolution and glxgears with 540fps

Question is, why is radeon not loaded before X is started? Is there a conflicting framebuffer device (I habe VGA framebuffer compiled in, no modules). Can I force loading radeon that on the kcmd line?
