Sorry about that. I got confused - too late a night. I thought that all
the Celeron options set the SSE2 flag but looking at it again, they
don't. I have a memory of a compile for PIII/Celeron which kernel
panicked with "processor doesn't support SSE2" but I cannot reproduce
this. 

My apologies once again,

figured out how to light the middle yet.
