As I recall, merely turning the support on would cause the screen init
function to do something which would result in a dmesg spew from the
kernel (something about the ctxsw fw being unhappy... maybe?). Since
compute didn't actually do anything particularly useful, seemed
easiest to just disable it. Sorry, I don't remember specifics.
