I use an untra-2(SMP) as a desktop with no problems,
kernel-2.4.27-sparc-r1. For me, on this system, kernels 2.6.x are so
unstable as to be unusable.

Sorry. It's a bug in xorg, and I never have pushed it very hard because I
keep thinking that kernel-2.6.?? should become stable on these systems
*almost any day now*. But that was my thought last December, and I might
revisit this.
I have tried as hard as I can to publicize the problem; I know that it is
noted in the sticky xorg-x11 forum thread and on my d.g.o/~fmccor site.

Can't comment; don't use sound at all.

Same comment about publicity. Please review the xorg-x11 tracking bug
79467 at
https://bugs.gentoo.org/show_bug.cgi?id=79467, get the patch, do what comment 6 says (except that it should now read
patch -p0 -b -z- < {path-to-xorg-x11-6.8.1.904-sparc.patch}
and rebuild xorg-x11. This will fix SDL problems for you.

I wouldn't upgrade. I would apply the patch and rebuild xorg for getting
SDL right. There is information around on sound support on U2, but I
don't have it. You might check #gentoo-sparc IRC or maybe the forums for
information.
Hope this helps,
