This should be fixed with 4b892e6b4435f6ff8916ac755a6014e0ca737b0d .
The attached patch restores i915 drm functionality at least for an i386 Lenovo Ideapad with Intel 945 graphics. It also should have identical functionality for x86_64 machines. The patch has been tested for x86_64 Intel integrated graphics G45 and HD Graphics. Basically the kmap / kunmap functions for i386 only are replaced by the previously used sf_buf functions.
The patch is against

kernel - Reduce ig4 receive errors
The whole point of using the kmap API is to reduce differences with Linux; I won't be reintroducing sf_buf usage.
Besides, the i386 architecture is now deprecated.
If you still want to use i386 hardware with DragonFly, you should consider moving to a stable 3.8.x release.

I'm sorry, the proposal was rejected.
i386 is officially no longer supported (prior to 4.0 release)
