This is quite different from memballoon. pvpanic is a single I/O port, it doesn't use up a PCI slot (thus causing conflicts with other devices at the same address). Perhaps this issue is simply fixed by making the _STA method return 0x0B instead of 0x0F (i.e. turning off the "show in user interface" bit).
