Actually, yes, I can run this on several other smaller-memory systems. 
I've got a machine I've been working on setting up that's 2GB exactly,
and several others running 2.4.19 & LVM 1.0.5 with less than 1GB of
ram.  However, I've not had any of these systems produce errors like
these.  I can run the 2GB system with and without high memory support
and try to induce a similar failure.

Are there any specific tests you'd like me to run on this other system,
in case I can't induce an Oops on it?

Thanks,

Gregory
