Zhenyu Wang 5fd4df4d47 drm: fix regression in fb blank handling
commit 731b5a15a3

    drm/kms: properly handle fbdev blanking

uses DRM_MODE_DPMS_ON for FB_BLANK_NORMAL, but DRM_MODE_DPMS_ON
is actually for turning output on instead of blank.

This makes fb blank broken on my T61, it put LVDS on but leave
pipe disabled which made screen totally white or caused some
'burning' effect.

[airlied: James objects to this but at this point in 2.6.33,
I can't see a patch that will fix this properly like he wants coming
in time and otherwise this is a regression - proper fix for 2.6.34
hopefully.]

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).

The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:

    1. The DRM provides synchronized access to the graphics hardware via
       the use of an optimized two-tiered lock.

    2. The DRM enforces the DRI security policy for access to the graphics
       hardware by only allowing authenticated X11 clients access to
       restricted regions of memory.

    3. The DRM provides a generic DMA engine, complete with multiple
       queues and the ability to detect the need for an OpenGL context
       switch.

    4. The DRM is extensible via the use of small device-specific modules
       that rely extensively on the API exported by the DRM module.


Documentation on the DRI is available from:
    http://dri.freedesktop.org/wiki/Documentation
