Description Bill Nottingham 2008-04-08 05:25:05 UTC 
Description of problem:

Using i915.modeset=1 to enable the modesetting kernel driver causes the kernel
to print out a message on boot about this being an unknown boot parameter.

It's pretty obvious now that 'quiet' mode is back on.

Version-Release number of selected component (if applicable):

kernel-2.6.25-0.204.rc8.git4.fc9.x86_64
Comment 1 Chuck Ebbert 2008-04-11 16:49:11 UTC 
It's not built in so you need to put that in modprobe.conf.

If this is happening on the live CD or install disk the parameter is working
because the code that loads the driver parses the kernel command line to pick
this up. There doesn't seem to be any good way of killing that warning though.
Comment 2 Bill Nottingham 2008-04-11 17:38:13 UTC 
See /etc/modprobe.d/i915modeset - it's set up to be configued via /proc/cmdline
Comment 3 Chuck Ebbert 2008-04-11 22:27:48 UTC 
So the kernel warning is bogus but there's no good way to kill it. Turning off
the warnings completely would make it hard to find real mistakes in the command
line.

Upstream has been debating this problem but nobody has a good answer yet.
