Modified Files:
        src/sys/dev/drm: drmP.h drm_drv.c drm_scatter.c

Log Message:
Rework scatter / gather page allocation inspired by r186295 of FreeBSD SVN:

    rework drm_scatter.c which allocates scatter / gather pages for use by
    ati pci gart to use bus_dma to handle the allocations.  This fixes
    a garbled screen issue on at least some radeons (X1400 tested).  It is
    also likely that this is the correct fix for PR# 119324, though that
    is not confirmed yet.

Fixes similar issues on a Radeon Mobility X300, non-Mobility X800 (including
a hard-lock of the machine).
