Robert,

Here's one thing you should address:

Index: std.sgimips
===================================================================
RCS file: /cvsroot/syssrc/sys/arch/sgimips/conf/std.sgimips,v
retrieving revision 1.12
diff -r1.12 std.sgimips
10c10
< makeoptions   DEFTEXTADDR="0x80069000"
---
> makeoptions   DEFTEXTADDR="0x88069000"

That TEXTADDR needs to be 88069000 instead of 80069000.  The O2
uses the 800xxxxx address.

Let me know if that resolves the issue.

I'm performing a "cvs diff" right now to update a log of where
I differ from the cvs tree.  I'll check for anything else 
differing in my tree.
