One thing to check: if you have openpromfs mounted you could see what /proc/openprom/<[EMAIL PROTECTED]>/sparc-version says. It should tell what SPARC version the CPU really implements (or claims to implement). I apologize if this has already been checked, but I couldn't see any evidence of it neither in the BTS nor the list archive. > Globally enabling kernel emulation of umul for sun4m shouldn't do any > harm, so that seems like the best approach.

If compiled-in the kernel could possibly check the above entry in OpenProm to decide and fall back to something safe if it's not. -- ilmari
