I have a display card + display combination that has recently had much problems during system boot. Some system versions boot just fine to very large text mode, others create entirely black display.
Is there any way to forbid the DRM from doing "maximize the text display area" operation at all during the boot? I do want the DRM/KMS to happen latter, but NOT during system boot!
