OK, that's what the current table says.

"Cooked only" in what sense?  Do you get the PPP header (with or without
an HDLC-like-encapsulation header)?  Do you get control-protocol
packets?  (The other BSDs should, I think, give you all packets,
including control protocols, at least with the kernel PPP
implementation.)

I may try to pester Jordan Hubbard about that.  (It might also make the
Wildpackets people happy, assuming that they use BPF for the MacOS X
EtherPeek and plan to do an AiroPeek for MacOS X and use BPF for that as
well.)
