10005	Support for VIA Nano X2 L4350 => Fixed in SVN	johanb		"The VIA Nano X2 L4350 processor supports hardware virtualization (Intel VT-x).

The CPU flag is recognized by VirtualBox:
{{{
00:00:00.369 VMX - Virtual Machine Technology = 0 (1)
}}}
But CPU  itself is unknown:
{{{
00:00:00.502 HWACCM: No VT-x or AMD-V CPU extension found. Reason VERR_HWACCM_UNKNOWN_CPU
00:00:00.502 HWACCM: VMX MSR_IA32_FEATURE_CONTROL=0
}}}
VirtualBox guests therefor don't have hardware virtualization.

Would it be possible to support this CPU?
