Unfortunately the last two kernel upgrades (2.6.34.6-54 and 2.6.34.7-56) didn't correspond to an upgrade of the kernel modules necessary by virtualbox (vboxdrv, vboxnetflt, and vboxnetadp); this impedes the normal behavior of virtualbox.
Did you try running "service vboxdrv setup"? That should cause it to build kernel modules for the running kernel. I have to do this every time I do a kernel update.
