It is if you can use udev and hal to sort out things.  Only thing is, if 
hal or udev doesn't work, you are stuck with using xorg.conf.  As some 
may know here, hal didn't work for me.  It was good at locking up my 
keyboard and mouse tho.  At one point, even the SysRq key wouldn't work.

I don't know where but I also read where someone had trouble with a LCD 
screen one time.  It would work on a console but no GUI.  They had to 
use a xorg.conf file to set the display up properly so that it would 
work.  Hal works for most people  but doesn't for others.  Then some 
others can do some minor tweaking and get it to work.

I wouldn't even think of trying to tell someone how to tweak hal's 
config file.  It's in xml and I can't read that.

I did find this link which may help.  The part at the bottom is what I 
think you need.

Hope that helps.
