Nah. You may be able to toggle a BIOS switch that says "yes, I really
want to run from the integrated graphics" without removing the
discrete card, though. All I'd really be able to tell you is "that
might be fixed in a newer kernel".

Sorry. KMS is kernel modesetting. This has been a recent change.
Previously, the X drivers did all the modesetting from userspace,
which required a lot of banging on the card as root. Moving all the
privileged code for modesetting into the kernel allows lots of
improvements. Here's a far better explanation than I could ever give:

The rub here is that the intel driver (and now radeon) have very
mature modesetting code for userspace that has to be ported over to
the kernel. This has mostly been done for intel, but people are still
reporting regressions (black screen on intel was one that was reported
