4.1.2 does not check for KVM modules in CentOS6

[zanzu]

I recently installed CentOS 6 including all the updates and the latest version of Virtualbox (4.1.2). The installation went flawless however, when I try to create a Windows7 guest, the entire system freezes and requires a reboot. I've tried to create the images on the SSD drives and SATA drives (same results). The only workaround is to remove the kvm and kvm-intel modules.

Should virtualbox check if the KVM modules are installed?

My setup is as follows:

Tyan S7025 2x Xeon 5650 24GB Ram 2x OCZ V3 240GB SSD 2x 500GB SATA 1x Nivida GTX590 CentOS 6 w/ kernel 2.6.32-71.29 x86_64 VirtualBox 4.1.2
