# console
You can get full console resolution on an Intel 945-series graphics adapter with 915resolution. Find some spare mode like 640x480:

    % sudo ./915resolution -l
    Intel 800/900 Series VBIOS Hack : version 0.5.3

    Chipset: 915GM
    BIOS: TYPE 1
    Mode Table Offset: $C0000 + $269
    Mode Table Entries: 36
    ...
    Mode 41 : 640x480, 16 bits/pixel
    ...
 
Set it to 1024x600 for example:

   % sudo ./915resolution 41 1024 600

Then load vesa:

   % kldload vesa

And use vidcontrol:

   % vidcontrol -i mode|grep 1024
