AMD 64-bit and Intel 64-bit confusion !

According to http://www.debian-administration.org/articles/534 Intel initially chose not to extend their IA-32 processor family to 64 bits, preferring to promote their own but incompatible HP PA-RISC based IA-64 "Itanium" processor family !

but then Intel adopted AMD's 64-bit extensions into their IA-32 processor family, calling them "Intel 64" (aka IA-32e and EMT64). Final generation Pentium 4 & D, Celeron D, and Xeon processors and all "Core 2" based processors now include AMD compatible 64-bit extensions.

To add to the confusion https://help.ubuntu.com/community/ProcessorArch lists a few dozen Intel processors but doesn't make it clear which type a Pentium DualCore is ! Which is what my Compaq A900 notebook says it has in it !

I have 4G of RAM that I have only been able to access 3G of so far (with 4 different OS's)

Update :
It seems that my Pentium DualCore has PAE (?) support and when I install from the Xubuntu x86 (32-bit ?) CD I CAN see all 4G ! So what benefits if any would I get from using the Xubuntu 64-bit (AMD64) CD instead ?

My SONY PIII says it is:
$ cat /proc/cpuinfo

vendor_id    : GenuineIntel
cpu family    : 6

Intel PowerTOP

Intel is releasing PowerTOP, a tool that helps you find what software is using the most power. By fixing (or closing) these applications or processes, you can immediately see the power savings in the tool. You'll also see the estimated time left for battery power if you are running a laptop.

PowerTOP is a Linux tool that finds the software component(s) that make your laptop use more power than necessary while it is idle. As of Linux kernel version 2.6.21, the kernel no longer has a fixed 1000Hz timer tick. This will (in theory) give a huge power savings because the CPU stays in low power mode for longer periods of time during system idle.

kernel virtual machine (kvm) virtualisation

There is yet another virtualisation technology on the block !

http://www.vizzr.info/2007/04/24/kernel-virtual-machine-kvm/

kvm only run on processors that supports x86 hvm (vt/svm instructions set) whereas Xen also allows running modified operating systems on non-hvm x86 processors using a technique called paravirtualization. kvm does not support paravirtualization for cpu but may support paravirtualization for device drivers to improve I/O performance.
kvm FAQ

Proprietary vendors take note :
Xen and kvm make use of Intel-VT and AMD-V hardware virtualisation features !
