flush_dcache_range problems

Anyone have an idea as to why flush_dcache_range is crashing the kernel on
my 603e based board? It's dying on the "dcbst   r0,r3" instruction. I've
been unable to find any other code that uses this function, so I don't
even know if it works on the 603 at all.

Thoughts?

PS- tomorrow's the last day I'm working on this project, so quick replies
are great :)

Thanks,
--Gus
