Sorry for my late response. With Driver "intel" and i915_load=YES in
rc.conf, I get a segfault when starting Xorg (I use Xorg from
ravenports):
70.937] (EE) Segmentation fault at address 0x0
[ 70.937] (EE)
Fatal server error:
[ 70.938] (EE) Caught signal 11 (Segmentation fault). Server aborting
[ 70.938] (EE)
[ 70.938] (EE)
Please consult the The X.Org Foundation support
at http://wiki.x.org
for help.
[ 70.938] (EE) Please also check the log file at "/var/log/Xorg.0.log" for additional information.
[ 70.938] (EE)
[ 70.942] (EE) Server terminated with error (1). Closing log file.
Driver "intel" works when I leave out i915_load.
Driver "modesetting" works regardless of i915_load.

I am using Xorg-server from Ravenports. I think the ports there lack
these patches.
How can I test if hardware acceleration is turned on? And will the
"intel" driver be more performant than "modesetting"? How can I test
this?
