So I got bold and enabled CONFIG_PREEMPT in 2.5.39, and got the
following message at boot time:

kksymoops is very nice :)

The system still seems to be running ok, but I think I'll turn off
CONFIG_PREEMPT just to be sure.

This is a SMP kernel running on a UP box.  Other configuration options
available if needed.

thanks,
