 I cannot reproduce the problem here.  Would you provide backtrace when
 the system page faults?
 
 Please make sure that the screen saver is in sync with the kernel.
 This is usually ensured when you `make world' and rebuild the kernel,
 though...

 I think this may be related to kern/10376 and possibly kern/10125.
 
 kern/10376 has a couple of backtraces attached and I still have the
 coredumps if you want more detail.
