I've had this problem throughout 3 different XFree86 versions 
(3.1.2, 3.2, and now 3.2A).  Using Linux 2.0.29 (was Red Hat 4.0),
a Panasonic CF-41 laptop with C&T65548 video, and the XF86_SVGA server.  

Mine will SIGSEGV consistently - 9 out of 10 times I switch from 
X to another tty.  This happens both in 8-bit and 16-bit color modes, 
apparently regardless of what is running. AHHH!!

It would be nice if, like everyone else, I could access the virtual 
consoles while running X.  

Does anyone have any insight as to the nature of this beast?

Thanks ahead of time,

Nelson Tibbitt
