You didn't mention whether you were using lilo or grub to boot. If you're using grub you can use the grub shell to figure that out. At least to the which are detected and numbering phase. I had that problem or something similar some time ago when updating to the new, at the time, pata drivers. I ended up using a brute force technique... I booted grub to it's built in shell and used it's limited tools to figure out which partition/drive was which and editing the kernel/initrd lines to get the system to boot to init level 1 and then make the changes permanent in grub and fstab. Probably an easier method would be to use a livecd. Just edit the grub menu.lst file and fstab to match your new layout. Or change the device.map to match the old layout.
