I get the same drop in bogomips, but I did not get a slower system... > This all seem to be compiler/bintools dependend (gcc 2.95 vs. egcs32) > and some People say, the 2.4.18 and up may be stable on not-ROSS-cpu's > and without smp.

I asked for this information on sparclinux@vger.kernel.org, but nobody answered... probably they did not like my mail ;) I will try to help if I can, but I'm a greenhorn concerning the kernel code... and sparcs. thanks emanuel
