Depending on the O.S. version you have, some don't have the kernel
tree in them(only initrd.img). look in /usr/src/ if nothing then, I
would suggest
compiling you're own fresh vanilla kernel.
i.g. apt-get install git-core or kernel.org
then make a dir where you like(mine is /home/kernel/)
then change into the directory and
 git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
linux-2.6
or go to kernel.org and download the .tar.gz or bz2
uncompress
then make menuconfig(you need to apt-get build-essential and libncurses5-dev)
once you see the screen pop up
you can see pci options in the main menu
in there you will find MMCONFIG.
after you've tweaked the configuration(how big or small you want you're kernel)
or use this one: http://www.odi.ch/prog/macbookpro/index.php#3
(just put it into the kernel tree as .config)
then exit and make the kernel.
(this is what I usually do<below>)
make
make modules
make modules_install
make install
then I make links i.g.
ln -fs /home/kernel/2.6.27-rc1 linux
cd /
ln -fs /boot/vmlinuz-2.6.27-rc1 vmlinuz
then update-grub
reboot and see the fresh kernel.

if you've already compiled you own kernel then ignore the above:
the MMCONFIG option like I said up top, is in the main menu of
make menuconfig. I think it says "PCI options" or soemthing like that.
