Intel included as well. :-)
In addition, IIRC the intent was also to provide a "flicker-free" boot, ie.
avoid having the monitor switch resolutions several times during boot. IOW,
it's not just a eye-candy plymouth boot, but also avoiding that ugly annoying
"click" that the monitor does when switching. Also, the virtual terminals look
much nicer in hi-res. :-)
Finally, the KMS idea is apparently more elegant code-wise, because it neatly
splits the kernel-side and user-side of the driver. At least in the nouveau
case --- they don't even support non-KMS driver anymore. I believe there is a
trend to do the same in the intel and radeon world as well.
All in all, bleeding edge software, and our own choice to run it... ;-)
Best, :-)
