What warnings? building X without using the current DRM? as I said the
X DRM is out-of-date, build X with DrmSrcDir set to a knew drm and it
should all be fine...

It wasn't an assumption, it was a design decision, the X server
creates 2-3 maps currently (framebuffer/mmio/agp), I don't think it
suddenly through any stretch of anyones imagination overflow 28-bits
... then again I could be proven wrong at which stage I'll be well
gone from the project :-)
