You can't.  If the device driver doesn't tell DEVFS to, it's because the
device does not exist.

Can you mail me the output of:

	diskinfo -v da0
	diskinfo -v da0s4
	dd if=/dev/da0 count=63 | uuencode - openbsd.sect0 
	dd if=/dev/da0s4 count=16 | uuencode - openbsd.slice4

Then I'll try to see what goes on.
