--- Comment #27 from Alex <alupu01 at gmail.com> ---
In anticipation of possible questions regarding the purpose of the
"video=HDMI-A-2:640x480M" parameter
I use in in the grub 'menu.lst' kernel line
(kernel ... video=HDMI-A-2:640x480M):

TESTS without "video=HDMI-A-2:640x480M"

1. Reboot, login (as root)
$
$ stty -a | grep speed
speed 38400 baud; rows 25; columns 80; ...

Start X (Level 5)
Exit X (return to Level 3

$ stty -a | grep speed
speed 38400 baud; rows 56; columns 240; ...
-------------------------------------------------
2. Reboot, login (as root)
$
$ stty -a | grep speed
speed 38400 baud; rows 25; columns 80; ...

$ modprobe i915

$ stty -a | grep speed
speed 38400 baud; rows 67; columns 240; ...
-------------------------------------------------

ANSWER
With the parameter "video=HDMI-A-2:640x480M" in,
I can at least "recover" my 80x25 console by using
the trick detailed in Comment #26.2 above.
