Your questions are best directed to the virtual consoles project
team[0].  Generally speaking, backwards BFU is not supported, so it
would not be surprising if you had problems after installing snv_74
and then bfuing to something based on 66.

In the meantime, use screen[1].

Preferred by whom?  The Sun-supported way to upgrade among Solaris
*releases* (which SXCE and SXDE are not) is to use the Upgrade
feature, including LiveUpgrade.  BFU is preferred by many ON engineers
for development and testing purposes because it is faster, but it's
not really the best way for end-users to manage their systems.

You're probably experiencing some form of panic-on-boot.  Edit the
grub kernel command line to add '-kv' so that you can stop in kmdb
when the panic occurs.  This will allow you to debug the problem.

On a "real" system, one would never use BFU.  The exact steps
necessary to recover depend on the nature of the problem, which could
be anything from VMware brokenness to a bad boot archive to a failure
to resolve BFU conflicts correctly.  You haven't provided enough
information to know.  One recovery strategy is to boot into the
failsafe archive to examine and correct problems with the root
filesystem or its boot archive.  Whether this is appropriate in your
situation is unclear.

It's open source software; anyone is free to distribute it in any way
they like.  So there will be as few or as many distributions as there
is a perceived market for.  The mere existence of multiple
distributions is not harmful to you; you need only use one of them.
At the present time, all architectural requirements are being enforced
at the OpenSolaris level, not the distribution level, so it will
remain possible for all distribution vendors to produce compatible
products if they wish (note that these requirements[2] are much
stronger than comparable efforts in the GNU/Linux communities such as
LSB).  Again, however, no one can force them to do so.  If you need a
consistent and reliable distribution experience, stick with Solaris.
I'm hopeful that Sun will continue to ship and support it in something
like its current form for many years.
