A comment w.r.t. generating hashed handles: there are some cases where the
radeon family of client-side DRI drivers do arithmetic to generate handles.  I
*think* this is only for AGP memory.  I have a suspicion that the X server may
also generate handles for the registers and/or the framebuffer by reading the
device's PCI bus address registers, but I would need to verify that.

Anyway, the point is that the handles can't be completely arbitrary for all
types of mappings, at least not without checking a lot of code...
