"Can't find root filesystem / error mounting /dev/root" when booting to new kernel


I am trying to upgrade my kernel from 2.6.18-274 to 2.6.39 for some wireless card drivers.
When I boot into the new kernel I get the "Can't find root filesystem / error mounting /dev/root" googling led me to this page http://fedoraproject.org/wiki/Common..._.2Fdev.2Froot
From what I am reading seems to be an issue with a driver for my SATA controller or HD, but I can't find what option I need to add to the kernel.
Doing a diff from the old initrd to the new one gives me the following:
Code:
root-> diff /tmp/kafter /tmp/kbefore 
6a7,8
> lib/dm-message.ko
> lib/dm-region_hash.ko
8a11
> lib/dm-raid45.ko
13d15
< lib/dm-region-hash.ko
16a19
> lib/dm-mem-cache.ko
Do I need any of those? not sure if I would need dm-raid45.ko as I am not running a raid.
I have the same SATA and IDE options configured for both kernels so not sure what else to look for, any help is appreciated.

Additionally here is the HW info:
Code:

I fixed it with the help of this link http://serverfault.com/questions/108...ystem-dev-root

Needed this option: CONFIG_SYSFS_DEPRECATED_V2=Y
