Is there any error message when it tries to mount the root file system?
Likely yes; so the problem would be that your initrd does not contain 
the right drivers for disk access.

* reboot with the CD
* adjust /etc/mkinitcpio.conf
The HOOK line looks at me like the following:
HOOKS="base udev modconf block filesystems keyboard fsck resume"
Try to remove 'autodetect'; it may strip modules that are needed by 
accident; 'resume' is necessary for s2disk.
* re-create your initrd
mkinitcpio -k YOURKERNELVER -g /boot/initramfs-linux.img
KERNELVER can be found out by
ls /lib/modules

Good Luck!
