Omnibook and Satellite linux driver

this might be helpful:
kernel: 2.6.31.5

Do I need certain drivers enabled as modules for the omnibook module to
compile?

Hi,
I have applied the patch and got past the error. But now I get this. Am I
missing something?
Thanks.

I have the same problem trying to compile the omnibook module.

I have Fedora 11 with 2.6.30.5 kernel.
