No, I don't have da0 in fstab.. here it is:
# cat /etc/fstab
# Device Mountpoint FStype Options Dump Pass#
/dev/mirror/gmb none swap sw 0 0
/dev/mirror/gma / ufs rw 1 1
/dev/mirror/gmd /tmp ufs rw 2 2
/dev/mirror/gme /var ufs rw 2 2
/dev/mirror/gmf /usr ufs rw 2 2
/dev/mirror/gmg /jail ufs rw 2 2
/dev/mirror/gmh /dump ufs rw 2 2
/dev/acd0 /cdrom cd9660 ro,noauto 0 0
When I say da0 is the boot device, I mean that's the device that
the SCSI card is presenting to the BIOS to boot off. So loader and
kernel get booted off da0, then control is passed to gmirror to mount
root and so forth.

Understood, but no, I'm not doing that. I have debug output from a
fully syncronized mirror now; after reboot, again, da0 disconnected
itself from the mirror:

[snip, I think you get the idea]
It however has no problems re-activating the mirror immediately
after boot when I ask it to.
It doesn't seem to be related to the order of devices in the mirror
either; the first device was da1, the second da0, this time.
