Wow, this booted.  Several people I talked to thought it was originally 
a serial console issue.  Judging by the several times I've chosen to 
build a kernel, it seems R4400 cache gets broken quite often.  I'll run 
a cvs sync now and try to build my own kernel, since this appears to be 
built from recent code.  Your kernel lacked a few things gentoo requires 
to boot, but it at least proves I'm not going insane over here.

A known bug?  Interesting.  I mentioned it many moons ago in #mipslinux, 
and Ralf seemed curious about it, but he said he looked in the kernel 
where the memory was detected and said he didn't see anything wrong 
there.  Anything I can do to help look into this bug and possibly fix?

It worked fine for me with printing :)

[root@angband root]# echo "Hello World" > /dev/lp0
[root@angband root]# echo "Wow, It works" > /dev/lp0
[root@angband root]# echo "Totally Cool" > /dev/lp0

^---  All printed out on paper, although scratchy.  I need new ink 
cartridges.  Canon BJC-620

Mind you, that's an ISA Parallel Port card I dropped in.  I noticed the 
SGI's parallel port never worked, so I dug up a spare and tried it.
