Error al instalar drivers Modem HSP56

[Jans Alzate]

Hola a todos.
Soy nuevo en el manejo de Linux.
Mi maquina es un Pentium IV de 1.7GHz, 256 de RAM.Y con una placa madre que 
tiene incorporado un modem HSP56 MR.
Instale Redhat 9 en mi computador, y busque los driver para el modem.
Conseguí el driver pctel-0.9.7-9.tar.gz, y segui las instrucciones de 
instalacion de una guia que encontre en internet.
Al ejecutar ./setup todo se instala bien y no hay error, pero cuando hago los 
insmod -f pctel y
insmod -f ptserial,
sale un error en este último asi:

Hint: You are trying to load a module without a GPL compatible license 
      and it has unresolved symbols.  The module may be trying to access 
      GPLONLY symbols but the problem is more likely to be a coding or 
      user error.  Contact the module supplier for assistance, only they 
      can help you.

Luego al ejecutar el comando lsmod aparece solo el modulo pctel en estado de 
"unused" y no aparece el modulo ptserial
Que estoy haciendo mal o que me falta para que pueda conectarme por fin a 
interner desde Redhat 9?
Les agradezco a todos los que me puedan ayudar.
Hasta pronto.
