drm driver reload script

Looks like you've made a start alright. As I've said, I've you're getting stuck
somewhere, don't be afreaid to pop up on #intel-gfx on irc. To speed up the
development you can also only reload the drm/i915.ko kernel module. It's a bit
tricky, so I use the attached script (you still need to compile i915.ko and
copy it into the right place, of course).

You also need to enable CONFIG_VT_HW_CONSOLE_BINDING, otherwise the fbcon
unbinding won't work and you can't unload i915.ko. Also, a 2nd machine with ssh
access is very nice in case the module-reloading failed - otherwise you'll just
be starring at a blank screen.
