Sun U20 supported, fully/partially working... or not at all?

For sure!  I just wanted to use FreeBSD on this kind of machine, but
falling back to Solaris 10 will be the answer if that is not (yet?)
an option.

I am not interesting in gaming here, so lack of 3D support isn't a
problem.  But because i had problem running an U10 (sparc64) in the past
with a Creator graphic card, i am suspicious here -- maybe without reason
(but nothing say the opposite).

Right, unless it is just _planned_ to acquire some of this kind of machine,
hence my questioning.
