An update.  It seems they got it fixed (in the next release)
 From ticket 2829:

Formatting of the previous message got ugly so I am reposting the 
corrected version:

The problem appears with pre-2.6.20 kernels only. The fix will be 
included into the next maintenance release. Since netflt driver always 
comes with source code those who urgently need the fix may apply the 
following patch to src/vboxnetflt/linux/VBoxNetFlt-linux.c (the path is 
relative to your vbox installation directory):

<     INIT_WORK(&pThis->u.s.XmitTask, vboxNetFltLinuxXmitTask, NULL);
 >     INIT_WORK(&pThis->u.s.XmitTask, vboxNetFltLinuxXmitTask, 

Then, kernel modules need to be re-built with

/etc/init.d/vboxdrv setup
