jf> ps just prints out the column headers, and top fails with
jf> kvm_open: kinfo_proc size mismatch (expected 768, got 1088).

jf>I assume this is due to actually using the amd64
jf> procfs.

No, the error message is due to a kernel/userland mismatch.

jf> Is there anyway to make this work?

One way would be to populate your jails with 64bit versions
of those programs that depend on kernel datastructures (for
example. any program that uses libkvm).
