AMD Turion MT-40 not properly detected?

Description
Until some days ago I had a Turion MT-40 CPU (mobile single core 64Bit) in my PC. Now that I switched to an Intel Pentium Dual-Core E6300, I realise that the option of installing a 64-Bit guest was not offered for the Turion, even though it is a 64Bit CPU, and I used to have a VBox Version that was supposed to offer this option. Strange enough, I was offered the option to activate AMD-V, which is to my knowledge not available for the Turion MT and ML lines for socket 754, but only for the Turion MK für socket S1.
Host was (and is still after the CPU change) Windows XP. I don't list my guests here for the reason that they have nothing to do with this case.

I am going to set up a test PC the upcoming week with my old board so I can attach a VBox.log file here. But I can assure that on my old installation the AMD-V option could be activated, I even had it activated, there was no error msg or something like that.

I found a backup which contains a log file from my previous VBox 2.2.4 installation with a working Gentoo guest. I attach it for a first lookup. 2.2.4 did not differ in this issue from 3.0.4.

The log shows that AMD-V is not used (HWACCM: No VT-x or AMD-V CPU extension found. Reason VERR_SVM_NO_SVM) and is even not available for this CPU (SVM - AMD VM Extensions = 0 (0)). There should be a check in the GUI if VT-x/AMD-V is available on the host (CPUID check) and the option to enable this feature is grayed in the GUI when this feature is not available. There will be no error message if you activate this feature with VBoxManage. OTOH I don't know when we exactly added the GUI check, maybe in 3.0.0 or later (3.0.4 should have it).

OK, I did a test with my old mainboard now. I can see now that it was indeed not possible to activate AMD-V since this option was greyed out, however it is activated in the checkbox by default, I think it would be better to leave it unchecked (see attached screenshot). The other issue still remains, there is no option offered to install 64-Bit guests, even though the CPU is an AMD64 one. Now that I haved switched to an Intel Dual Core I have this option inside my Windows XP 32-Bit, but with the AMD I had not (see second screenshot).

Option of installing 64-Bit Linux guests not offered on AMD Turion 64 Windows XP 32-Bit host

Replying to Marcus Schätzle:

This is not a problem because 64-bit guests require VT-x or AMD-V on VirtualBox. Therefore no 64-bit guests without this host processor feature.

We have an internal defect for taking care of the GUI detection. It's probably a duplicate of some other ticket too, so I'm closing this one.
There is not much we can do without a VBox.log file. According to wikipedia, the MT-40 does not have support for AMD-V so I would be surprised if VBox really offered the option to enable AMD-V support for a VM.
