>Description:
invoking 'startx' completely freezes CURRENT built from cvsup of 20031217.
No panic, no messages, no nothing to go further on.
Hardware is a Thinkpad X20 part no. 2662-34U with a Rage Mobility P/M AGP 2x 4MB card.
Problem first occurred after building and installing CURRENT from end of November 2003 (something like 20031122).  Since this was a transition over the "64bit statfs hump", I initially thought that this was a problem with something in userland that needed to be recompiled.  I have since completely de-installed and re-built from scratch every package with a forwards and backwards dependency on XFree86-4 with the same results of crash.
Running xf86cfg works, making me suspect a problem with the "dri" module, but my knowledge of XFree86 is getting dated so the obvious route of commenting out "dri" and "glx" module load in XF86Config still results in a freeze.

I believe
>How-To-Repeat:
Install CURRENT on same hardware; invoke 'startx'.
