If you mean PVR SGX, no, I don't use it myself, and it's not a binary
driver, the code is open:
http://meego.gitorious.org/meego-os-base/kernel-source/trees/master/patches

The one I use is tidspbridge which is in staging.

But that's not relevant, what is relevant is that is that the API was
broken without a warning grace period in final releases. "Good"
drivers are broken, I suspect many that haven't made into mainline yet
will receive a bad surprise. Making this only a warning on .36 doesn't
hurt anybody, does it?
