If it was the one in the middle of the RAM slots, that's the L2 cache,
and I assume it is, since the one in my 7600 didn't cooperate with the
my nPower400 card either.  I didn't have anything to replace it with,
so I just took it out.  I really should get a better one for
performance reasons, but I just haven't done it yet.

Do you always use BootX?  I've never even tried it...

Well, that's definitely a different place than it crashed for me in
2.2.2 and 2.2.5, and I never tried more than a little at any of the
2.2.0pre kernels.  Maybe I'll take a look and see what changed...

Thanks.  If you have any modules, could you include them too?  I'd
appreciate it.
