Bootup after VB Guest Additions install, with Address Translation

After a clean install on VirtualBox, with no options (graphics, time zone, anything) changed, and an install of VirtualBox Guest Additions, after boot-up, ReactOS crashes to the Blue Screen of Doom.

Steps:
1. Install ReactOS from Trunk
2. Install VirtualBox Guest Additions
3. Reboot

VirtualBox 4.1.2, Ubuntu 11.10 (32bit, AMD Athlon 64 3800+). Tested ReactOS r55801 from the trunk builds page.
