All of my work was done in Splack, rather than Debian.
Looking at my notes - Sun4d UP needs my patches which are in 2.4.29
Sun4d SMP is still broken, and fixing it is beyond my skills.
There are 2 known issues, possibly related.
1) Serial console corruption
2) SMP instability seems to be IRQ related

I will try Sarge in the next few days and report back, but I suspect 
that I will need to upgrade to 2.4.29 or later.
AFAIK nobody has done any work on 2.6.x for Sun4d.
