Since multiple framebuffer maps are not supported any longer (commit
41c2e75e60200a860a74b7c84a6375c105e7437f) these maps would be broken,
and they are not used by the drm anyway.
Leave it to userspace to create one working map instead.

I think there is not much interest for supporting multiple framebuffer
maps at the moment, so I would suggest pushing this patch, hopefully
into 2.6.40, so there is a chance of reworking the savage userspace
(DDX and mesa) to deal with it instead.
