I've seen this too on i386, but never on some sparcs I have which have
higther disk load and get more power outage (they're running network
monitoring tools) so I suspect it's a hardware problem; maybe the
disk reordering writes in its cache. If this is true, a journaled
filesysten won't help.

BTW, if you're ready to do some hacking it's easy to set up a NetBSD
system with read-only disks, using a MFS or freshly-newfs'd filesystem
for things wich needs disk write access.
