Subject: Refine SCREEN_INFO sanity check for vgacon initialization
From: Gerd Hoffmann <[EMAIL PROTECTED]>
Refine SCREEN_INFO sanity check for vgacon initialization.
Checking video mode field only to see whenever SCREEN_INFO is
initialized is not enougth, in some cases it is zero although
a vga card is present. Lets additionally check cols and lines.
