let's revert to the old xdm for now.  this one should be easy.
can someone work on it please?

we should fix it to be disable-able.  i don't think the default
should change.  [*]

i've not heard back about anyone using the now-re-addded old
intel driver yet, but AFAICT, everyone either had success with
dropping the old driver binary in place or using 'modesetting'.

i was hoping to find time to bisect the intel driver tree from
the 2014-snapshot to the top of tree to find where the display
issues appeared, but perhaps we should switch back to the old
driver for now until i or someone has fixed the new one..


[*] i wonder if a hack to make to force a lower parallism for
some subdirs would help these systems.  eg:


and the (new) .MAKE.PARALLEL would set the -jN value for this
sub-make, allowing other sub-makes to be run concurrently,
but only N in llvm.
