Ah, thanks.  I was talking to Dave about it in IRC and it sounds like
we can let the DDX driver add the front buffer map and let the DRI
driver set it up without breaking the shared private struct.  I've
attached three patches (on top of my dri2 work) to illustrate the
idea.  What's missing is the i810 specific setup in mesa and a
mechanism to indicate whether or not dri_util.c should map the buffer
or if the DRI driver will do that.  But that's all behind the DRI
interface, so it's not a big deal.

I'm not sure why we're doing this though.  It looks like things are
mostly working as it is, it's just not very elegant.  And if we're
about to shake things up with DRM memory manager enabled DDX and DRI
drivers, do we want to add a hack like this?
