   I'm running 8.1_STABLE on PRGMR, and I'm running PV. They have a menu
item on their console interface to provide "system details", which
should confirm it for you.

   The last message I got from them on the subject wasn't completely
clear, but it sounded like they thought they could adjust a couple
things, move us to new hardware, and things would go on as normal. So
I'd follow up with PRGMR support before doing anything.
