That should allow to use a filter instead of an ithread handler, solving a great number of problems with pre-loading of DRM drivers and allow them to be statically compiled into the kernel as - unlike ihtreads - filters work right from the moment they are set up during attach. In turn, that would make the lack of a VESA driver for vt(4) less painful and likely even forgivable, as resolutions higher than VGA could be used way earlier, etc. Mariushome | help
