And for VPN in Windows *and* using WinPcap, one can check if this device
exist:
  \Device\NPF_GenericDialupAdapter

(controllable using 'sq query rasdial'). This works if you use
PPTP or L2TP but not OpenVPN.

BTW, a VPN on Windows doesn't come back up automatically after
a sleep/hibernation. The WOSB tool at http://www.dennisbabkin.com/wosb/
could be handy. What happens with your VPN on Linux (?) after coming
back from sleep/hibernation? Automatic or you need to script that too?
