What is this good for?

KotOR uses a series of scratch framebuffers for drawing the framebuffer
effects. These have no depth and no stencil, so check_compatible()
rejects them, subsequent GL calls are no-op, and the screen becomes
garbage. I also experimented successfully with disabling the visuals
that have no depth or no stencil in
gallium/state_trackers/dri/dri_screen.c, but I concluded that this one
was a smaller hack.
