There was just a thread about this on the honeypot mailling list
(honeypots () securityfocus com).  Not only can you make the OS undetectable,
you can also fake other OS's in the nmap scan.  Links from honeypot threads:

There are kernel options (TCP_DROP_SYNFIN) you can set to blackhole OS
guessing.  Check the honeypot archive for specifics.
