VirtualBox 3.2.4 Kernel Panic at Boot

[Kris Moore]

Running VirtualBox 3.2.4 here on 8.1-Beta1 - amd64:

FreeBSD pcbsd-5315 8.1-PRERELEASE FreeBSD 8.1-PRERELEASE #1: Tue Jun  1 
22:41:58 UTC 2010     
root at build8x64.pcbsd.org:/usr/obj/storage/builds/pcbsd-build81-x64/fbsd-source/8.1/sys/PCBSD  
amd64

Got the new VB 3.2.4 built, and installed. Works just fine when I first 
load and kldload the modules. However when I go to reboot, the vbox 
modules are causing a kernel panic almost immediately after ZFS inits:

Disabling the vboxdrv / flt / adp modules causes it to boot normally 
again. The kernel is pretty much just GENERIC with some ALTQ / pf goodies:

Note that 3.1.8 works just fine on this system...

Here's the /boot/loader.conf:
