Yeah, that's exactly how it is supposed to work...

probably. untested deb line, as this isn't in the archive yet.
Will test that sometime.

+ <p>sun4c CPUs are <em>not supported anymore</em> in sarge.
+ The support for sun4d CPUs is in a rather unknown state since they
+ are very rare. It is possible that sun4d CPUs with an MMU work.</p>
+
+ <p>sun4m CPUs are still supported but you need to install a newer kernel
+ version first before upgrading the system. This is because newer
+ versions of glibc use assembler instructions not available on certain
+ machines, so you need a updated kernel first that emulates the missing
+ instructions.</p>
+
+ <p>Technically only <em>some</em> sun4m chips are affected, but as
+ glibc can't reliably detect whether a system is affected it
+ will refuse to be upgraded on any 32bit SPARC system before a
+ fixed kernel is installed.</p>
+
+ <p>For those interested in the gory details: Some of the
+ sun4m chips, produced by Cypress/ROSS, don't implement the
+ <tt>umul</tt> instruction (RT601/CY7C601, same chip, only different names).
