Grab:

ftp://ftp.redfish-solutions.com/pub/915resolution-0.5.2-2.i386.rpm

(or conversely, grab the .src rpm if you want).

This repackaging will create entries in /etc/sysconfig and /etc/rc.d/init.d/
to integrate a little better on RH/FC than the version you get from the
author.

Oh, and I've found that Dell makes LCD monitors that frequently have
slightly incorrect DDC parameters.  To use a 2005FWP over VGA, for
instance, I had to use:

ModeLine     "1680x1050 (Dell')" 146.2 1680 1784 1960 2240 1050 1053 1059 1091

and not the:

ModeLine     "1680x1050 (Dell)" 146.2 1680 1784 1960 2240 1050 1053 1059 1089

that the DDC reported (or else the top 3 scan lines would be off-screen).

I've had similar issues with a Dell 2405FPW.
