I just finished working on a Via C3-mini ITX box, also with a vr0 interface;
it's not a laptop, but I felt it needed to suspend anyway. Suspend into S3
causes the vr0 to hang on resume, in my case with regular vr0: watchdog
Solution: reset the driver.
Implementation: build a custom kernel with _no_ vr interface built in. Make
sure vr is built as a module. In the suspend script, unload the module. In
resume, reload it, then run rc.d/netif and rc.d/routing. For simple machines
with uncomplicated interfaces and routing, that ought to do the trick.
