this is actually caused by a BIOS bug/kernel bug (depends who you talk to). It's because the BIOS has tables in the DSDT to represent the possible different video cards that would ship with the box (UMA or discrete). There is a fix available upstream, but it causes regressions on other machines. It will need to be tracked until it's ready.
