Aiyah.  I must have broken MIPS1-only configuration.  Earlier this year
I made changes in TLB handling which takes effects MIPS1-only kernel.
I got another panic report about MIPS1 TLB miss, so this issue
definitely needs to be solved before 1.5.   It's strange since my
MIPS1-only kernel made no TLB miss for long time since then.

Is anyone out there experiencing a similar trouble w/ MIPS1-only kernel
these days?

Yes, it was very helpful to me.

Should not, but 'options MIPS3' seems necessary at least for DS3100 this
moment.
