It shouldn't need much if any changes, due to the controller being
integrated.

The video memory is an area of system DRAM which the video controller
transparently DMAs from. This has the disadvantage that at high
resolutions and colour depths, you tend to get some flicker when the
system is doing other things (tying up the memory bus/DMA controller).
