You more likely find help on dri-devel mailing list for this, last time
i compiled miniglx (few month ago) it almost worked out of the box.
You might consider looking at dri-devel, mesa-dev, or xorg mailing
list archive for people talking about miniglx, i am sure you can find
out an old mesa version with miniglx working. That said using lastest
git might need you do some hacking in the drm, fb, mesa, miniglx,
but Airlie might have a more up to date miniglx in his own repository
see gitweb.freedesktop.org for list of public repository (his one should
If you got time you can also start working on egl or drm modesetting
which will likely be the future (ie modesetting in the kernel which
will replace fbdev and future) but this kind of project is time
consuming especialy if you don't know much about graphics hw.

Without the source i would say it's not possible unless you mimick all the
xf86 driver interface which basicly mean redo an xserver :)
