Do you have agp.ko loaded from loader.conf ? If not, what happens
if you add it there ?
The i915kms does have a dependency on agp, so it should have been
auto-loaded if not loaded explicitely. And agp should be probed at
least.
Loading i915kms from loader.conf is something I do not encourage
right now, since you loose VGA console somewhere during the kernel
startup.

Hmm, I probably see an issue. Please try the patch below.
