Have you looked into using a MTX_SPIN lock where Linux actually
employs a DRM_SPINTYPE one? 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.
