As a side note, I just tested VirtualBox-1.6.4-OSE.tar.bz2, pruned and 
built with pkg-virtualbox svn r336, and it doesn't improve this issue 
either. Actually I haven't been able to boot 2.6.26-2-686 successfully at 
all so far, while 2.6.25 continues to work reliably.

2.6.26 kernel guests from other distributions, like Ubuntu and Fedora 
rawhide seem to trigger it just as well, just like 2.6.26.2 with the 
current -stable queue (v2.6.26.1-25-gb501dc6) applied.
