I don't know between 3.5 and 4, but I'm pretty sure that there are significant improvements.  I know that I was using the E1000 nic driver and he said that the vmxnet3 driver was 2 to 3 times faster than it.  When I configure an XP workstation with it, it shows a connection speed of 1.4gb.  This comes from the upgrade from hardware version 4 (esxi 3.5) to the hardware version 7 (vSphere 4).  I'm talking about the VM hardware revision.
You should go 64-bit and ESXi 4 if there is any possible way.

Certainly there is enough experience and options on these lists to comment.

Wondering if the "real world" performance difference, if any, between
ESXi 3.5 (32 bit) and 4.0 (64 bit) is worth having to go hunt up an
"approved" 64 bit machine?

Guest performance, of primary interest.

I have several older servers that accept (and seem to run) 3.5, but,
sigh, none that accept an install of 4.0.
