I uninstalled the RPM for lirc. I got the source from CVS and 
setup/compiled it. now ls -al /dev/lirc* gives me

crw-r--r--    1 root     root      61,   0 Feb  2 12:53 /dev/lirc
srw-rw-rw-    1 root     root            0 Feb  2 11:39 /dev/lircd=

However, if I reboot something (devfs?) is removing /dev/lirc and 
replacing it with /dev/lirc/0 thus:

ls -l /dev/lirc*
srw-rw-rw-    1 root     root            0 Feb  3 20:02 /dev/lircd=

/dev/lirc:
total 0
crw-------    1 root     root      61,   0 Dec 31  1969 0

Before rebooting (while /dev/lirc was *still* a tty), I started lircd, 
then ran irw. This time, irw did not exit immediately; however, it did 
nothing when I pointed the remote directly at the receiver and pressed 
random buttons. I used ^C to exit and examined the logs. It appears that 
the kernel oops still occurs, though lircd doesn't report any strange 
errors.
