[SLL] Upgrading from 32bit to 64 bit

[Kurt Buff]

All,

I've got an Ubuntu 7.0.4 (Feisty Fawn) 32bit installation with 5g RAM,
and a small problem - probably mostly ignorance.

The purpose for this machine is to run several Win2k3 VMWare instances
under the free version - VMWare Server - for testing.

Obviously, Ubuntu doesn't recognize the extra gig of RAM, and I'd like
to rectify that situation.

I *think* (and am definitely open to correction) that the high-level
steps to upgrade would be to update the kernel to 64bit,  and then
recompile all of the userland stuff to match. I would not be surprised
if I had to get new VMWare licenses for a new 64bit version of that as
well.

However, I've inherited this box, and am much more of a FreeBSD guy
than a Linux person, let alone an Ubuntu devotee.

Anyone have experience doing this kind of stuff, and can point me in
the right direction?

Kurt
