VirtualBox doesn't see processor's PAE and NX capabilities?

When I try to install Windows 8 on VirtualBox, it stops soon into the install, with this error: http://i.imgur.com/VaHgDCd.png, which from what I understand means the computer doesn't have NX/XD capabilities. But the host computer does: http://i.imgur.com/TzSV4Y1.jpg, http://bpaste.net/raw/e0c5db4cedda and PAE/NX is enabled in this VM's settings: http://i.imgur.com/7Nx7XxO.png. When I try to install Windows 7 on VirtualBox, a similar thing happens: the installer stops, complaining the machine doesn't support PAE.

I asked on the VirtualBox forum, but they aren't willing to help much because (from what I understand) I'm using Arch's build rather than the official binary.
Any ideas what I can try to do to solve this?

Possible clue, possible red herrring: I recently switched host machines. Basically, every piece of hardware except the hard drive and video card is different. Installing Windows 7 worked on the previous machine (not Windows 8, though; it lacked VT-x or something).

I still haven't been able to find any further information about this. Does anyone have any ideas?
