No. That would require that Linux wireless drivers generate PPI headers; I don't know of any that do.

That's all that the Linux drivers support.

Kismet on Linux will *generate* PPI headers *itself* based on whatever radio information is supplied while capturing, such as the radiotap header, and on GPS data it gets. It is not receiving PPI headers from libpcap.
Wireshark doesn't have a GPS interface, so any data it put into a synthesized PPI header would be data from a radiotap or Prism or AVS header; there's no point in synthesizing a PPI header for that - it just puts out the radio header that already exists.
