WITHOUT_NEW_XORG not fully supported on stable/8?

[ Discussion moved over to X11 list where it belongs better; subject adjusted ]

tl;dr: It looks like WITHOUT_NEW_XORG support is not complete (e.g., missing
checks in graphics/libdrm port), otherwise thanks for supporting it!  Yet I
fear it will go away sooner rather then later; how feasible would be extend
the life of low-level UMS bits and provide necessary compatibility shims for
modern upper-level stuff (like libGL/cairo/KDE)?

Well, first suggestion would be actually respecting WITHOUT_NEW_XORG knob as
advertised; particularly, it looks like graphics/libdrm should include this
checks, maybe something else (haven't looked closer yet).

We've discussed that before with dumbbell@ et al. on IRC a number of times,
I fully agree with this, no need to argue. :)

I did not ask for 100% support of new KDE with all its bells and whistles; I
merely was expecting to get a working X11 with WITHOUT_NEW_XORG set, yet it
broke.  How realistic would be having pre-KMS stuff in ports for bare-boned
X11 (sans KDE) available at least while we still support 8.4?  You've listed
a lot of components that need to be taken care of, but can't we have modern
cairo working with UMS libdrm/drivers/xorg-server, with compatibility patch?
Or, would it be feasible to patch the last UMS-aware version of x11-drivers/
xf86-video-intel so it can work with new xserver?
