adding driver to installation image

[Eric Doutreleau]

Hi

i have the following problem
i used to network installation of fedora 9

but today we get dell optiplex 760 with intel 82567LM-3 gigabits.
the problem is that there s no driver for that card in the initrd.img 
file of the installation image.

For previous version of fedora i succeed in adding a new driver but i 
didn't find a way to do it the F9.
is there any documentation in doing that?

Thanks in advance for any help
