  We show that a classical result of Gromov in symplectic geometry extends to
the context of symplectic foliations, which we regard as a $h$-principle for
(regular) Poisson geometry. Namely, we formulate a sufficient cohomological
criterion for a regular bivector to be homotopic to a regular Poisson
structure, in the spirit of Haefliger's criterion for homotoping a distribution
to a foliation. We give an example to show that this criterion is not too
unsharp.
