We are. PCB in person said so, so we should be safe:
Phillips, Peter C. B. & Jin, Sainan, 2002.
"The KPSS test with seasonal dummies," Economics Letters, Elsevier, vol.
77(2), pages 239-243, October.

Actually I thought it was already in the original KPSS article, but this
is also good to know.
I committed some modification to CVS so that the kpss command now
accepts a --seasonals option.
very nice, thanks.
