Looks OK, but you should get the interrupt level message when starting X.

I haven't seen yet DRM working *without* Yorick's patches, YMMV.

mkdir /dev/dri ; mknod /dev/dri/card0 c 180 0 (AFAIR - see above;
can't check right now as my laptop is being booted from a Indiana
Preview 2 live CD - impressive stuff, BTW);

chmod 0660 /dev/dri/card0

modular-xorg 1.3 should do the job; 1.4 is good as well, but if you go
this way, you will have to change many packages' Makefiles (adding
references to buildlink3.mk for libXdamage, libXcomposite and pixman
here and there).

On my Intel 945 I was unable to get the latest Intel 2.2 driver to
play game, so I am still back to 2.1.0 (there should be something in
tech-x11 archives from the last few weeks).

Xorg -configure should make the right (almost) xorg.conf for you;
perhaps disable AIGLX and composite to begin with (as per the man
page).

Keep fingers crossed ... if you get a black screen with a blinking
cursor in the top-left corner with no way to break into debugger or
ssh, may be you also should try the older version of the
xf86-video-intel driver, as myself.
