Thanks to all of those who responded to my message in such a timely
manner.  The utility of a mailing list like this was certainly
demonstrated.  

I had several solutions offered:

1.  Type several CTRL-C's during the load of vmunix bringing it back
to the console prompt.  This would probably work as long as long as
the ROM's service interrupts.  I didn't try this solution.

2.  Type several CTRL-C's during the file system check (fsck) pass.
Again this would probably work but I didn't do this either.

3.  Open up the case and short the jumper that clears the ROM, or at
least it sets the ROM to factory defaults.  I looked upon this as a
last resort approach.  

4.  The approach I took was to turn on the machine with the disc
drives powered off.  This was the easiest for me since I had powered
everything off while I thought about a solution.  The autoboot
sequence immediately failed and I got a console prompt.  I was
expecting to have to wait for a lengthy timeout but it was very quick
to figure out that the boot device wasn't there.  Once I was at the
console prompt I removed the -a switch from vmunix and entered single
user mode to fix my /etc/rc.local.

Again, thanks to all of you who offered these solutions.
