Could the root device now be referred to as /dev/sda4 (SCSI Disk  
support) with the kernel now loading?
You should be able to pass the root device to the kernel at boot time  
(root=/dev/sda4).
If you are able to get past the root filesystem check (the disk is  
referred to as sda instead of hda), then you will need to update your / 
etc/fstab to reflect the different device names.
