That's why I wrote that it is for drm2 and i915kms on 9.3-STABLE.

I don't understand. With the patch below, I actually _have_ i915kms
and drm2 statically in the kernel on 9.3-STABLE. It boots, switches
to graphics mode during boot and Xorg starts fine. I can switch
back to the console with ctrl-alt-f1 and even scroll back here --
at least up to the line 

info: [drm] Initialized i915 1.6.0 20080730

And of course I can switch back to the running Xorg...
