I'm running NetBSD -current (about 1 month old) with a 4 disk raid0
partition (a news spool).  Last night one of the disks hiccupped.  Now the
raid0 set will not work.  The disk itself seems fine, but raidframe will
not let the disk back into the stripe.  It says "/dev/sd16e has a different
modfication count: 147 88".

Is there a way to force raidframe to accept this disk?  The data will be a
bit inconsistent, but fsck should fix that.  It's a news spool so a few
missing or corrupted files are okay.

I'm appending the dmesg output.
