DRI on NetBSD 5.x/amd64 i945GM - black screen

[David Brownlee <abs%absd.org@localhost>]

I tried to setup dri on my amd64 laptop using the notes at
http://wiki.netbsd.se/DRI%2C_AIGLX%2C_Composite_and_Compiz

Unfortunately starting X hangs with a black screen. Does anyone have
any thoughts/help?

The relevant lines from dmesg are:

i915drm0: Initialized i915 1.6.0 20080730

and from Xorg.0.log
