PMC power


I will try to make this question as simple as possible.

When designing a 5V or universal PMC card

is it safe to assume that 3.3V will always be present?

or are there any host slots out there that do not supply 3.3V?

(in which case one should just bypass the 3.3V pins
and include a 5V -> 3.3V regulator or converter
for the local 3.3V power plane.)
