[Suns-at-Home] Seti at Home on Ultra 80 or E420R? Can it be done?

[machine1]

I have a Netra t 1405 (Same motherboard as Ultra 80 or E420R) with four 
440MHz processors, 4 gigs RAM and a GFX8P frame buffer/graphics board. It's 
served quite nicely as a general purpose, rather imposing looking desktop 
machine with Solaris 10 and Star Office. I rescued it from a data center 
upgrade/downsize junkpile. I've been in the Seti @ Home project since near 
the beginning and have the BOINC Seti @ Home running on several Windows 
boxes. I've spent hours trying to get it to run on my Netra and I've come to 
the conclusion I'm not enough of a Unix guru to make it work without going 
back to school. Has anyone here managed to get S&H running on an Ultra 80 or 
E420R?  I've tried the distributions listed on the Seti @ home website, and 
many links are dead, and the ones I can get to have to be edited and 
compiled.
