DRI success on Thinkpad x40 (i855GM)

[Tobias Nygren <tnn%NetBSD.org@localhost>]

Well, I finally got DRI to work on my laptop and thought I'd share
the stuff I used:

* NetBSD-current kernel as of today with "i915drm* at vga?"
* wip/modular-xorg-server 1.4.0.90nb1
* x11/xf86-video-intel 2.2.1
* wip/MesaLib 7.0.3rc2
* wip/glx-utils

I had to make a clean xorg.conf with "Xorg -configure", my old
1.3 config just gave me a blank screen for some reason.
Hope this helps somebody.

Cheers,
-Tobias
