Write a driver and we'll talk. Until then, I don't think your argument
is well supported.

If the result is that your driver requires a completely separate
interface than the Intel driver, that's OK too  -- we can talk about
merging them together in some unified mechanism at that point.

I'm trying to get from zero to one kernel driver for Intel graphics at
this point; that seems a valuable goal in itself. I hope it leads to
other people building kernel drivers for other graphics hardware. Don't
let me stop you from building a better mousetrap if you think the code
I've written is wrong somewhere.
