Just for my personal understanding, can you explain me what does it means that "there is no standard VGA graphic mode at all" and what make you say that?

No luck also with the new patch.
I've applied it to the original file, not to the one with your previous patch, is that correct?
It's not rendering anything because the led of the monitor turns from blue to orange, just like when the pc is turned off and the monitor is on.
This happens running vidcontrol -i MODE_X where X is one of the modes of type "G" (as I've said I had to comment the allscreens_flags line in /etc/rc.conf). And if I subsequently switch to another ttyv with alt+f[1-8], the mode is not the default 80x25 as normally expected and the led is still orange and sometimes the speaker plays a beep!
