Subject: [PATCH] uterm: vt: keep graphics mode during VT switch
If we open a VT, we assume that we are the only user on it. Therefore, we
put it into graphics mode _once_ and keep it this way. Resetting it to
text mode is useless, as there is no other user and every VT has its own
modes.
This also fixes page-flip issues during VT-switches which caused the
text-mode fbdev layer to claim one vertical-sync for their own page-flip
only for us to override it immediately after it is done.
