OK, now a lovely little E8400 power my machine which is VT-x and VT-d capable.

Well. Still no 64 bit option and System/Acceleration tab is disabled
in my Virtualbox. Any idea why? Motherboard? BIOS?

My system is:
"Linux artifex 3.2.0-3-amd64 #1 SMP Mon Jul 23 02:45:17 UTC 2012
x86_64 GNU/Linux"

dmesg:
"[    0.051573] CPU0: Intel(R) Core(TM)2 CPU         E8400  @ 3.00GHz

vboxdrv related lines (what and why legacy support warning?):
