300Hz clock rate

Well, ATSC (HDTV) is at 24/30/60 frames per second, exactly.

Except nobody I know uses 30 fps video. NTSC is 29.97 fps. Or is that 30000/1001 fps?

... This means Core Duo, Pentium-D 9xx (not 8xx) ...

Actually, being a Pentium-D 9xx it's not enough. It needs to be 9x0.
As an example, a Pentium D 940 has VT support, while 945 doesn't.

The hardware (your cpu and motherboard) have to support VT (intel) or AMD-V (or SVM) to use this.

This means Core Duo, Pentium-D 9xx (not 8xx), and Xeons. Maybe a couple others. I have one. Pentium-D on a Asus 945G. (Nice.)

You need to have support in the motherboard also. If you don't have support, but you feel your cpu should support it.. look for a bios upgrade to add support.

For AMD any AM2 socket CPU except Sempron will support the SVM stuff. Also telling is if your AMD cpu supports DDR2 then it will support the extesions.

The userland stuff is essentially a slightly modified Qemu VM.

The linked page is unclear, but I seem to remember that you need special hardware (new processors basically) for that, am I wrong?

And will probably become very useful very fast. http://kvm.sourceforge.net/

KVM also supports AMD's virtualization extensions (not just Intel's).

Correction: LRW (Liskov-Rivest-Wagner) is a mode of operation of block ciphers, meant for use in disk encryption, but is not a block cipher by itself.
