Hmmm, pretty od really. pvdisplay calls the pv_status() lib function
which retrieves the information from the kernel. That's why i asked for
the proc output which shows that the PVs are _active_ and allocatable.

Wait, need to preserve the core flags to make this work...

Could you test if the following patch to pvdisplay.c helps ?
