So, I'm not sure how many people this will actually affect(!), but
I've just switched over the pc532 port to using generic event counters
(evcnt(9)) for tracking interrupt counts, and removed some pc532-only
code from vmstat(8).  This means all you -current users will need to
rebuild vmstat if you update your kernels.

Cheers,
Simon.
