OK well, I *still* think at least disable if <1GB RAM.
else your get flooded with data corruptions and/or kernel panics as
ZFS's IO pipe will stave the kernel of its memory and render the
system unresponsive or in the worst case, just panic.

I can't stress this any more ! Although 64Bit is just a
recommendation. I feel >=1GB of RAM *should* be made a _requirement_ !

I hope I am being very clear on this warning,
