I bypassed this with a very simple modification to the file:
/usr/share/virtualbox/src/vboxhost/vboxpci/linux/VBoxPci-linux.c

Thank you for the report. Similar fix applied. Actually that code deserves more maintenance but right now there is no time for that. The fix will be part of the next 4.3.x maintenance release and also part of the next 5.0.x Beta. Please use the forum to report problems in Beta releases (I know, this time it made sense to use the bugtracker).
