This belongs here. For several tests the size of the available 
framebuffer memory needs to be known. It's stored in 
mdev->vram_fb_available. mgag200_mm_init() sets the value of 
mdev->vram_fb_available to the full size of the video RAM. The line 
above subtracts the size of 2 cursor buffers.

Thomas
