In an ideal world, you shouldn't be forced to update anything except 
some/all of the driver bits.

But the fact that libdrm is lumped together as it is, and that mesa is a 
monolith, forces you to update a more significant portion of your 
system. You have to resort to some serious manual labour to get around 
that atm.
