Hello @misc,
I do not see a reason not to update OS version that vmt (kernel level
implementation of VMware Tools) is advertising to VMware hypervisor from 32
bit FreeBSD to 64 bit version.
If for nothing else, there's clock running forward issue that appeared in
7.2 release and that is solved simply by manually specifying "FreeBSD
64-bit" instead of "FreeBSD 32-bit" for "Guest OS Version".

Attached is a simple patch that I tested and that changes string "FreeBSD"
to "FreeBSD-64" in a call to "SetGuestInfo" function on hypervisor and that
accomplishes the task.
What could be a drawback? Is author David Gwynne still active and can he
give some feedback?
What versions of ESXi did you test this with?
Did you test both i386 OpenBSD VMs and amd64 ones on each version?

Mike, good point, I forgot about i386 and so I actually did install a
new OpenBSD i386 Guest on ESXi 6.5.
Also have adjusted a patch for vmt to send 32-bit OS identifier for i386
and 64-bit identifier for amd64, it is attached here.
Tested on both guest on same hypervisor, ESXi 6.5.
