Oh, so it's not much different than solving the problem of lost root password on a linux machine. And finally it is clear that I am presented with a console login, not ALOM.
Editing the /etc/shadow file is something I did couple of times on Ubuntu, so I am familiar with root pass recovery. However, in this case I don't think it is going to be THAT straightforward. I have a CD-ROM on the V100 machine and no floppy, and my outdated lab computers aren't able to burn a LiveCD image for me since both have DVD-ROM's. And no USB boot capability on my V100 either, since OpenBoot firmware is older than the recommended version.
Network installation of a LiveCD to the rescue? Is it possible to network boot a LiveCD without ANY intervention on the client? Is it possible to use a Windows machine as a boot server that will host the LiveCD image? I can't get past the console login screen let alone edit files on the V100 machine...
P.S. I found an OpenSolaris LiveCD image for SPARC machines and I hope it'll work for me.

twiglet
TWIGLET(1) User's Manual TWIGLET(1)
NAME
twiglet - observe or control an RVC-enabled machine's console
SYNOPSIS
twiglet [OPTION]... host-specification
DESCRIPTION
twiglet is a program for controlling another machine's console. It works using the RVC protocol, and an RVC server (such as rvcd(1)) must
be running on the machine to be observed.
Using twiglet, the a best effort attempt is made to duplicate the screen contents of the observed machine. If the machine is displaying a
virtual text console, the text on the console is rendered in the terminal in which twiglet runs. If the machine is displaying an X ses-
sion, and the RVC server supports VNC integration, twiglet will open a window that contains the current contents of the X display.
It is also possible to control the observed machine in various ways. With keyboard control enabled (and with support from the RVC server),
keys may be sent to the observed machine in text console mode almost as if they were typed from the keyboard. Twiglet also supports
switching virtual console on the observed machine. Finally, if VNC integration is available, the X display can be manipulated almost as if
the user were at the console.
The intended use for twiglet is in training and teaching environments. The idea is that there are student machines and a control machine
(which the trainer or teacher would be using), with a serial line attached to each student machine. The trainer or teacher can then ana-
lyse the students' attempts to complete tasks, and help them out (showing them how to finish it) without needed to push them aside to get
to the keyboard.
This client is written using ncurses(3X).
OPTIONS
--help display a help message and exit successfully
--version
display a version number and exit successfully
-c, --control
control the remote machine rather than just observing it
-e xy, --escape xy
set the escape character and the escape escape character (like screen(1))
The host-specification takes one of the following forms:
host:port
to connect to an RVC server over TCP
tty [host]
to communicate with an RVC server over a tty (for example a serial line); the optional hostname is for VNC integration
BUGS
I'm sure there are bugs, but I don't know what they are.
