I see.  In general there's no way to discover that revision
number from any of the information presented by the Sun
Ray firmware.  The -NN may change to address an issue
that the firmware doesn't know about or care about, so
there's no corresponding firmware change and therefore
no change in the version strings reported by the firmware.
For instance, the firmware wouldn't know or care about a
VGA output analogue circuit change or a power supply
replacement, whereas either of those events would cause
the -NN to roll.

Once in a while there'll be a hardware change that does
require a matching firmware change, and in that case the
firmware update will bring with it a new 'boot" version
string.  But the boot version string can also change
because of a firmware update that is not tied to a hardware
change.  For instance, the update might deliver a bugfix
or a new feature.

Based on the "boot" values I have looked at I got the impression that
this was hardwired (i.e. on a regular chip with no way of flashing it).
Right? Wrong?

The "boot" firmware resides in FLASH, so in theory it could
be overwritten, but as a matter of policy we never overwrite
it.  So in practice the "boot" string tells you the upper bound
on the age of the unit.
