I have RH70 on Compaq EP with Intel 810 AGP video. Sometimes when I'm
switching between VTs (text <-> X) the Xserver dies with signal 11 shortly
after switch from text to X. 

I've tried XFree86 v4.0.1a and also v4.0.2-11 from Rawhide, both crashed.
I've tried i686 glibc v2.1.x (default rh70) and now v2.2-12 (updates). I
have 192MB RAM and 200MB swap.


Steps to reproduce (sometimes)

   1.Launch X, run some apps (netscape, mozilla, xterm) 
   2.Work som time (maybe it depends on memory usage or time runnig X). 
   3.Repeat switching to text VT and back to X

   ... and Xserver crashes
