With your informatitions about your disk, it's better to set the index 
for your hdaX to the same index as your native installation, than the 
cobdX is the same as hdaX.  And better, you use alias to real hdaX, that 
makes the /etc/fstab more easy.

This should work for you (coLinux 0.6.4):

<?xml version="1.0" encoding="UTF-8"?>
<colinux>
     <!-- cobd1 is your SWAP partition -->
     <block_device index="1" path="\Device\Harddisk0\Partition1"
     alias="hda1" enabled="true" />

     <!-- cobd2 is your SuSE Root -->
     <block_device index="2" path="\Device\Harddisk0\Partition2"
     alias="hda2" enabled="true" />

     <!-- Define your Root partition (not the Boot) -->
     <!-- Lets start a runlevel without graphic -->
     <bootparams>root=/dev/hda2 ro init 3</bootparams>

     <!-- Initial RamDISK (initrd) and Kernel from coLinux -->
     <initrd path="initrd.gz" />
     <image path="vmlinux" />

     <!-- this line allows you to specify the amount of memory
          available to coLinux -->
     <memory size="128" />
</colinux>

This all is in assumtion, that you would run your native Linux under 
colinux.  Is this right?

Please remember, that you need some changes on boot scripts in your 
SuSE, before it would be run properly.  Follow the title in wiki:
