What operating system(s) are you using?  Depending on the operating system
what you desire could be a trivial task.  The laptop and the internet
connected desktop(?) computers could be networked via their serial ports or
parallel ports.  Via the serial ports you could setup a SLIP (serial line
IP) or PPP (Point-to-Point Protocol) connection.  Via the parallel ports you
could setup a PLIP (Parallel Line IP) connection.  Either way you would have
a local two computer IP network using these interfaces for your network
interfaces.  The laptop would be setup as an ordinary host and the desktop
would be your router.

The laptop would not hae to know anything about the modem it would just know
that it would have to send all of its network packets to the router which
would be its gateway.  If you are using dynamic IP address on your rouer to
connect to the internet, the router would have to masquerade the packets
that it is forwarding from the laptop.  Again, depending on the operating
system this can be trivial.
