Some additional info:
I noticed that the boot output I included in my original report is
perhaps a bit misleading, in that it shows the BT946 SCSI controller
(a PCI device) being probed along with the other ISA devices. This is
because I had enabled the 'bt0' device in the 'Storage' section
of the visual kernel config screen to see if that worked better than just
allowing the BT946 to be auto-discovered as a PCI device. (It didn't.)
So, FWIW, here's a (verbose) boot output reflecting what I assume is the
more correct kernel configuration:

With this kernel configuration, one sequence of events that happened to
culminate in a panic was the following:
- boot from floppy, install bin distribution on newfs-ed file systems
- reboot from hard disk, enable dump device in rc.conf
- reboot again, drop to single-user mode via shutdown(8)
- run /stand/sysinstall, select some additional distributions
The kernel panicked while installing the selected distributions,
resulting in the following stack trace:
# gdb -k kernel.0 vmcore.0
