A *very* important thing about vgatext, is that it won't natively
support suspend and resume. It is a generic VGA driver that has no
way of really knowing how to restore hardware in a generic way. I
also suspect that the bug mentioned below is a "Will Not Fix", as
there is no way of being certain that the fix will work on all
hardware that it binds.
Usage of the lable mentioned below should be strongly discouraged
for general use, and has value *ONLY IF* the user does not care at all
about the state of the VGA device across a suspend and resume cycle
(say, you are using a serial console, and there is no monitor
connected to the VGA port).
Work on the i915 driver to support your framebuffer would be
valuable (assuming that it isn't already underway or completed), but I
strongly suggest not doing this work on vgatext, nor setting
vgatext_force_suspend.
Cheers!
