The same problem occured in a desktop system with 82865G (link). (This is a kernel bug.) PATCH_ALREADY_AVAILABLE, (831 bytes, Xorg falling back to use FBDEV driver. with. If KMS is switched on, the framebuffer console support must be selected. KMS is required for using the xserver-xorg-video-nouveau package. Blacklist the nouveau kernel module, e.g. On Intel and Radeon cards KMS is disabled at run time in Debian kernel images by default.1 It is enabled via modprobe configuration files provided by the xserver-xorg-video-intel and xserver-xorg-video-radeon packages. After more investigations I've found, that the problem is related to framebuffer console. 800×600 on a 1024×600 panel. In my systems (self compiled kernel without initial ramdisk) I had to to set CONFIG_FRAMEBUFFER_CONSOLE=y, CONFIG_FRAMEBUFFER_CONSOLE_ROTATION=y . If you are a new customer, register now for access to product evaluations and purchasing capabilities. Therefore the workaround mentioned in the previous point was not applicable any more. Your Red Hat account gives you access to your profile, preferences, and services, depending on your status. It also provides native-resolution VTs on some laptops and netbooks which, prior to this, would use some standard mode, e.g. Are any of these also applicable to radeon?

Kernel Mode Setting (KMS) provides faster mode switching for X and console.

[Another report:] On my 945GM, CONFIG_FRAMEBUFFER_CONSOLE must be built-in, and not built as a module (this will require building-in AGP / DRM / Intel / Consoleframebuffer) Kernel Bugzilla. The same "painful" process happened when the control was given back to the X server (Alt+F7when X runs in VT7). Display is faling for [AMD/ATI] Oland GL [FirePro W2100] graphics card on RHEL 6.
