I looked into the specs of all Pine boards, but I could not find any hint about a number of additional I²C busses beyond the single one on the Pi-2 connector.

Like I wrote in a message to Ian, if FreeBSD does keep up the 32bit support, 32bit or 64bit is not a matter of concern for me. If Pine really got a number of I²C busses, then I would like to learn about this. However, the LTS part of the Pine A64-LTS is no more that much appealing, since it ends in less than 2 years from now. What about the Pine Rock64Pro or the Pine H64, do these also offer additional I²C busses?

Ideal would be a SBC for which the FreeBSD support would be (almost) ready to get started now, and this board is either new enough so chances are that it is available in the next several years (perhaps the Pine RockPro64) or there is a successor for on outdated but perfectly working board lurking, for example like BBB -> BBAI. In the latter case the expectation would be that I could port FreeBSD to it, perhaps with the help, hints, recommendations, etc. of knowledgable people on the FreeBSD-ARM list. 

Thank you very much.
