Ok thank you all for your replies.
I'm thinking I can't use amd64 on a PIII, right?
So, given that I'm stuck with this particular piece of hardware, my
only real option is to begin down the long and scary road of PAE. Yes?

I have an IBM xSeries 350 4xPIII with 5.5gb of RAM, and see that

amn't
quite sure I know which part of the situation is the real problem.
Is it a limitation of the i386 port? That is to say, if there were
a specific PIII (i686?) port, would this problem be overcome? Or is
it a hardware limitation? Is it necessary to use a not-clean method
to access the extra address space (is this what PAE is?), and
there's no clean
way around it, regardless of the port?
I was looking at building a PAE kernel, but was discouraged by the
lack of usb and certain SCSI support, both of which I'd really like
to have (in the case of SCSI, need to have). Is this lack of
support because of an inherent difficulty in the hardware, or could
it be overcome in a stable way with modification of the device
driver code?
My basic (and very hypothetical) question - if I had unlimited time
and knowledge (I have limited both), what direction would I take to
get access to all 5.5gb of RAM on this particular computer?
Thank you,
Bob
It's a limitation of the basic i386 architecture; you have to use
i386 with PAE, or better yet use amd64, because those architectures
support memory address sizes beyond 32-bits.

Correct.
