I gave up trying to understand TTM (they don't make happy pills that big)
and used GEM and a simple allocator. The private allocator GEM change
means you can now use GEM to magic up objects that are in on card or
stolen memory where applicable not just backed in system memory.

That depends on your libkms for the device. You can allocate a one bit
deep object if you want. Reading libkms source is probably what you need
if you've not already done os.

Which I think means a modern X will not care about the hardware cursor ?
