Description of problem:
When running 'startx', the screen blanks and the machine deadlocks completely
(keybd LEDs do not respond, network ping does not respond). This happens when
DRI is enabled (and it is enabled by default). Removing the "DRI" section at the
top of /etc/X11/CF86Config and also commenting out the 'Load "dri"' line in the
Module section of the same file allows X to start successfully. This bug has
been around since at least RH 7.3.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Just run 'startx' with the default XF86Config file provided by the RH 8.0
Actual Results: System deadlocks as described.
Expected Results: X desktop should have eventually appeared.
Hardware configuration is a little 'interesting':
2 CPU SMP P2-450 XEON
Intel 440 GX chipset
PCI Voodoo 5500 card --note PCI, not AGP
Please attach your X config file, log file, and the output of the following:

Diff showing changes to original config file (disabling DRI) --X starts ok with this config

`lspci -vn` output on machine exhibiting deadlock

Info from /proc/version
Cannot post X log file because machine deadlocks before any data gets written to
the log. If you have a suggestion on how to work around this, I'll give it a shot...
Please upgrade to Fedora Core 2 or later, and if this issue turns
