Yes, I do have "kern.vty=vt" enabled in the loader and without i915kms
loaded my system boots correctly. I can load i915kms later per hand
or when starting X, but it does not work with bootloader.

I think it's a known problem as of September 2nd as stated on the
http://wiki.freebsd.org/Newcons page. (My machine is Sony VAIO SZ5MN).
