In Fedora, a patch has been added which does this:

       -H <host-name>
              Specify the host-name option to send to the  DHCP  server.   The
              host-name  string only contains the client’s hostname prefix, to
              which the server will append the ddns-domainname or  domain-name
              options,  if  any,  to derive the fully qualified domain name of
              the client.  The -H option cannot be used with the -F option.

Here is the changelog entry:

* Sat May 06 2006 Jason Vas Dias <jvdias at> - 12:3.0.4-1
- Upgrade to upstream version 3.0.4, released Friday 2006-05-05 .
- Add new dhclient command line arguments:
  -H <host-name> : parse as dhclient.conf 'send host-name "<host-name>";'
  -F <fqdn>      : parse as dhclient.conf 'send fqdn.fqdn "<fqdn>";'
  -T <timeout>   : parse as dhclient.conf 'timeout <timeout>;'

The patch is in Fedora CVS here:
