Some preliminary info is in the DJGPP FAQ list (faq102.zip from the same 
place you get DJGPP), chapters 10 and 18.  You might also look at the 
following packages:

Game programming:

             - Try the Jlib gaming/graphics library, at
               ftp://x2ftp.oulu.fi/pub/msdos/programming/djgpp2/jlib_NNN.zip
               written by J P Griffiths <jpg AT cs DOT waikato DOT ac DOT nz> .

VGA Mode-X graphics:

             - Paul Fenwick <bg914 AT FreeNet DOT Carleton DOT CA>  wrote an X-Mode
               package Xlib, at
               ftp://ftp.delorie.com/pub/djgpp/contrib/xlib_dj2.zip  or Xlib
               at OULU, at
               ftp://x2ftp.oulu.fi/pub/msdos/programming/djgpp2/xlib_dj2.zip

Latest DJGPP v2.0 beta releases support direct access to the VGA, look in 
the libc docs, under _enable_nearptr (sp?).
