Lowlevel video output switch controls? Modulized, why?
Hi
Well, i use Arch on my laptop. And there is one thing, which makes me wanna jump on it. 
The Lowlevel video output switch controls kernel module. I need this activated in order to switch between the projector and my laptop, I have my finals soon so its important this works as it should.
Would it be possible to enable this module in later pacman-versions of the kernel? At the time beeing, I would have to recompile everything my self. Which I have yet to become successful at, something is always wrong. But I`ll summarize what I would like to do:
#Build a kernel with this option, choosing it from grub at boot-time. But still have the "pacman-version" in case i mess up somethings up.
NOTE I use luksEncrypted root, does this option do anything to the kernel? Since the installer asks if you need to boot from an encrypted volume. Just asking...
Anyway, can I just download the kernel source. Run make menuconfig, activate the Low level video output switch controls. Then -> make modules_install? And then copy the kernel-version over to boot, and use it? Or what else?
Thank you so much for helping, took me ages discovering this feature was disabled on purpose.

How do you use this kernel option?
(and why don't you use xrandr 1.2)

These are already enabled in the 2.6.25 kernel in testing.
