Using HAL for X Server Config Properties?

Actually the X Server has to have quite a bit of knowledge of the
underlying hardware, particularlly on the display side if you want to
take advantage of such things as HW Accelerated 3D. The question of
multiple X servers is an interesting aspect that I hadn't considered.
One question however, why would adding a x11 properly any different that
what has already been done in HAL for ALSA ??
My real goal here is to investigate what should tbe the proper approach
so that the X server can make use of the hot plug infrastructure of the
underlying Linux system so that we can move away from manually
re-configuring the X server every time a hardware change is made.
I've CC'd this onto the xorg mailing list also.
Thanks.
