Can't compile Omnibook module

[Martinux]

Hi everybody.
First of all, sorry for my English.

I'm using Kubuntu Gutsy Beta on my Toshiba Satellite M70, which is not supported by the kernel module "Toshiba" and "Toshiba__acpi".
I've found a module called omnibook (omnibook.sf.net), it helps Linux to correctly recognize my notebook's hardware (ie: bluetooth, battery, ecc ecc).
With Feisty I was able to compile and run the module but now it does not compile...
The result of make is:

root@ubuntu-laptop:/home/omnibook-2.20070211# make
make -C /lib/modules/2.6.22-12-generic/build SUBDIRS=/home/omnibook-2.20070211 modules

This is a big problem for me because my notebook needs that module...
What can I do?

Thanks, Martino.
