Understood now, Adam.

I have no FBSD VM, but just about every other OS vms. LeoOSx, Win7(32&64), 
Several XPs, several 2003, Fedora and even an OS/2 warp. They all work. In 
fact, LeoOsx and Win7 (32) are up as I type this.

The problem comes IF I change the rendering engine from Xrender to OpenGL. 
Or even if a GL screensaver kicks in.

With OpenGL, Win7 freezes the host even before the login prompt, XP may run 
for 5 or 50 minutes and freeze, so does the all other OSes (except Fedora but 
it has no GUI)

Here is my env:

- Phenom II 955 black
- 8G Ram

- FreeBSD Papi 8.0-STABLE FreeBSD 8.0-STABLE #0 r204106M: Tue Mar 16 23:17:32 
UTC 2010     root at Papi:/usr/obj/usr/src/sys/LOBO  amd64 <- csuped yesterday !

- (II) Mar 17 19:44:28 NVIDIA(0): NVIDIA GPU GeForce 9800 GT (G92) at(GPU-0)
- (II) NVIDIA dlloader X Driver  195.36.15  Fri Mar 12 08:49:20 
posix/SystemV/PST 2010 <- compiled yesterday ! New release.

- virtualbox-ose-devel-3.1.51.r27187 A general-purpose full virtualizer
- virtualbox-ose-kmod-devel-3.1.51.r27187 VirtualBox kernel module for FreeBSD
Latest port with Mac Support !

- KDE 4.3.5

Like I said on my last e-mail, The new driver improved on the old. With the 
195.22 driver, the host would freeze even if I had Xrender enabled, and Lord 
knows how many syctl and boot tweaks I tried.
