My pleasure!
I've updated the bugzilla I started at:
https://freedesktop.org/bugzilla/show_bug.cgi?id=1333
to include the information below. Hope this will help to find the
problems!
================================================
Tested three different graphics configurations:
(all are at 1024x768)
16 Bit, DRI = No.
16 Bit, DRI = Yes.
24 Bit.
*****************
16 Bit, DRI = No.
*****************
Open up a terminal session
The sequence:
<CTRL><ALT><F1>
Took me to the text login screen.
<CTRL><ALT><F7>
Brought me back to the terminal session I left.
During the terminal session I ran glxgears and an odd thing happened
when I exited the program. Notice the last line here:
-------------------------------------
[root at linmaster log]# glxgears
771 frames in 5.0 seconds = 154.200 FPS
600 frames in 5.0 seconds = 120.000 FPS
720 frames in 5.0 seconds = 144.000 FPS
600 frames in 5.0 seconds = 120.000 FPS
600 frames in 5.0 seconds = 120.000 FPS
720 frames in 5.0 seconds = 144.000 FPS
600 frames in 5.0 seconds = 120.000 FPS
600 frames in 5.0 seconds = 120.000 FPS
600 frames in 5.0 seconds = 120.000 FPS
X connection to :0.0 broken (explicit kill or server shutdown).

This is my normal setup mode. I have booted this computer 100's
of times into this mode without problem until today (after the
24 Bit test below)
Open up a terminal session
The sequence:
<CTRL><ALT><F1>
Took me to the text login screen.
<CTRL><ALT><F7>
Caused the computer to lock up without re-displaying the graphical
login screen. I had to reboot.

This was a disaster. All the nastiness described in
https://freedesktop.org/bugzilla/show_bug.cgi?id=1232
occurred;i.e. the slowness and refresh problems.

What's also puzzling, is that even the 16Bit, DRI=Yes mode
above was a problem after running this configuration
(slowness and refresh problems). I finally had
to do a cold boot in order to restore things to working condition.
(Mounting the root partition on another OS (FC1) and copying the 16
Bit, DRI=Yes Xorg.conf file into place and then reboot into Fedora
Core 3
Also of note is the fact that I am certain that I've run 24 Bit
graphics on an earlier version of Xorg-X11 software without
problems. If it will be of use to troubleshoot this problem I'll
be happy to roll back to earlier versions of Xorg-X11* software.
