    Description

      On some Gfx-Cards videoprt.sys fails to init because it detects too many access ranges due to legacy shadowed mem areas.

      It can be avoided by using the videoprt.sys from XP. This will list one range less!

      Confirmed cases and differences using XP's videoprt.sys instead of ReactOS's:
      Sis630 on Uniwill 340s8:

      I/O 3c0 - 3df 
      I/O 3b0 - 3bb 
      I/O ac80 - acff 
      Mem a0000 - bffff <- XP's videoprt.sys on ROS & XP does not list 
      Mem c0000 - cffff 
      Mem dfee0000 - dfefffff 
      Mem d0000000 - d7ffffff

       Sis760 (Mirage 2) on Uniwill 255KI 

      I/O 3c0 - 3df 
      I/O 3b0 - 3bb 
      I/O cc00 - cc7f 
      Mem a0000 - bffff 
      Mem c0000 - cffff <- XP's videoprt.sys on ROS & XP does not list 
      Mem dfee0000 - dfefffff 
      Mem d0000000 - d7ffffff

       
      Trident Video Accelerator Cyberblade i7 on PCG-9415
       

      I/O 3c0 - 3df 
      I/O 3b0 - 3bb 
      I/O cc00 - cc7f  <- XP's videoprt.sys on ROS does not list 
      Mem a0000 - bffff 
      Mem fb800000 - fbffffff 
      Mem fb100000 - fb11ffff 
      Mem fc000000 - fc7fffff

      More will be added as soon as confirmed with working gfx-driver...
