Only Vista can depending on the correct bit, right?

Yeah, 32-bit XP to 32-bit Vista will work, 32-bit XP to 64-bit Vista won't.

XP to anything on Windows 7 won't upgrade. However, Windows 7 does offer
to back up all of your old Windows files into a new directory structure
called "Windows.old", which can be used to revert to XP at a later time.
Your old "settings and documents" folders will also be backed up here.

Windows Vista and 7 are much closer to the way Linux handles IRQs now.
Distributes them out amongst 16,000+ IRQ ports, and only shares them if
they are really part of the same peripheral.

16K? Wow.

Yeah, I don't expect to ever see an IRQ-related problem in these newer
systems.

While I waited for 64-bit Windows to mature, I did have 64-bit Ubuntu
running on my system, even before I went over 4GB. I'd been running
64-bit Ubuntu since version 5.04. It was fairly mature already at that
point, and just as well supported as 32-bit Ubuntu.

Cool. I still use 32-bit because it works fine. It only had 2-3 GB of
RAM on the old Debian installation from 2005. Maybe I will go 64-bit
when I reinstall it from scratch whenever that is.

As far as I'm concerned, with any distribution of Linux, I see no reason
why anybody should be running 32-bit Linux at all, even if they don't
have more than 4GB of RAM installed.
