You may get errors with the X driver of the form
_X11TransSocketUNIXConnect: Can't connect: errno = 111
It's a kernel bug. The function sys_iopl in arch/i386/kernel/process.c
does an illegal hack which used to work but is now broken since GCC
optimizes more aggressively . The newer 2.1.x kernels already have a fix
which should also work in 2.0.32.
