I'm not one of the "official Xorg developers".
However - maybe we can still successfully solve your issue, despite the
fact that I am a complete total newbie without any prior experience.
First, Xorg has its roots in pre 2004 XFree86.
So it should normally work at least as well with a given config, as an
older XFree86 (like in your case) did.
The CL-GD5446 is old, but had once been quite widespread in the mid

First, how did you try to configure X?
Maybe Fedora includes some configuration utility and maybe the mistake
already happens there.
Try the following and report the results (and also the Xorg log file) :
Xorg -verbose -logverbose -configure
Also, doesn't xorgcfg bring X up properly?
If that didn't work, did you already try xorgconfig (manual text mode
setup) with conservative Monitor sync settings and afterwards xinit?
Even if the device specific driver does not work, you then
should still be able to use VESA as interim solution, until the rest
is fixed (wich should not be too problematic actually).
Probably only a more conservative (lower) horizontal sync range of your
monitor might be the solution.
Please be more verbose.
