How about
http://www.postgresql.org/ftp/projects/gborg/uniqueidentifier/stable/

I think you're right:

PG_FUNCTION_INFO_V1(uniqueidentifier_out);
Datum
uniqueidentifier_out(PG_FUNCTION_ARGS)
{
    char *result;
    uniqueidentifier *in = (uniqueidentifier *) PG_GETARG_POINTER(0);

    if (in == NULL)
        PG_RETURN_CSTRING (NULL);

...and...

CREATE OR REPLACE FUNCTION uniqueidentifier_in(cstring)
    returns uniqueidentifier
    as 'MODULE_PATHNAME'
    language 'c';

It should use PG_ARGISNULL(0), no?
