I'm looking for code in assembler (GNAT/DJGPP format) to 

1) Draw a line in a memory area (linear addressing, 1 byte per pixel)

2) Copy a buffer from a memory area to VESA video memory
   with VESA 1.2 bank switching or using VESA 2.0 frame buffer
   ( Is it faster when 2.0 is emulated ? How to get the address
   of frame buffer ? )

3) Swap the display between 2 video memory areas without moving images
   ( Is it possible ? Is there a reliable method to determine whether
   swapping is supported and has enough video memory ? )

Thanks in advance for bits of information or useful URL's !
