Well it is not a typo, but it may be implemented off standard.  The 
setting really is 640 x 400.  The idea was to match the character 
display setting.  Maybe that is non-traditional for graphics.  The 
character display is 640 x 400 since it is 80 x 25 characters using an 8 
x 16 pixel font.  And I think that is traditional MDA compatible alpha 
mode 7.

It is possible to change it to 640 x 480 and change the pcx file, but 
the gmode implementation would need some registers changed.  I was lazy 
and it did not seem that important.
