I have no experience on solaris or SMP machines so just putting a hypothesis..

You may still run linux on a 8-10 way sparc. With O(1) patches available for
2.4 series, it should scale much more gracefully than earlier. It may not touch
solaris in scalability and fine grained resource control like disabling a
processor, but all in all, might be faster in performance vis-a-vis solaris.

At least it doesn't hurt trying if you can spare time and resources. Many
people say that linux outperform solaris on 1way/2way machines. If you could
find out what happens at 8 way, it would be great..:-)
