One serious regression compared to xorg-server 1.7.6 I've found during the
weekend is that video driver autodetection no longer works with xorg.conf.d in

For instance I'm using the following snippet to allow preferring fglrx and
radeonhd driver if installed.

        case 0x3d3d:                driverList[0] = "glint"; break;

This no longer works. If "fglrx" driver is not installed the Xserver just
gives up, i.e. no longer tries to use "radeonhd", then "ati/radeon". There is
no xorg.conf in place (I'm aware that this mechanism never worked with
xorg.conf in place), but xorg.conf.d is. After removing xorg.conf.d the
mechanism works again.

If there is a way to specify priorities for video drivers in xorg.conf.d
(matching vendor IDs) to replace that mechanism please let me know.
