yes, that changes everything!. Now it works (with the --data-length option)

thanks.

I finally got a chance to test this with FreeBSD (nmap 4.01)

and guess what, it doesn't work for this one host. Regular ping works.

so I am forced to assume this host is able to differentiate between a
normal ping and an nmap echo request ping.

As Omar noted, most OS-provided ping utilities send some data with the
ping packets.  If you add "--data-length 32" or "--data-length 64" to
your Nmap command, does that change anything?

Cheers,
