Right, we are not going to support SMP on sparc32 for etch.

There have been some improvements on the SMP front, but it is still
not ready for showtime (one of the latest examples is bug #400372 ).
If you are interested in the progress, you can check out the archives
of sparclinux mailing list , this question pops up periodically

Yes, the manual is outdated (bug #389516 ). sun4c is not
going to be supported by etch either.

Ouch. Just to confirm, what kernel was this machine running when this

sort this out, if it's not a hardware problem.
