I have actually some drafts for "drmSetMaster/drmDropMaster" man-pages
for libdrm on my machine. However, I am still waiting for my other
man-pages being applied to libdrm (they're pending on the list).

The drmSetMaster() man-page does explain the DRM-Master mess in all
detail, so I'd like to wait for this being reviewed before adding the
same information to kernel-docbook (if that is required at all).

David
