Wrote to you separately as I do not want to mess up the previous 
message.  If you noticed the reference to the launchpad bugs, I was one 
of the 'reporters' of the bugs. I can assure you the bug has been 
resolved long long ago.

What you did in removing the search line is wrong and you can rectify 
this at karmic by doing again "sudo grub-install /dev/sda" and try again 
if this boots to opensuse. But it's best you recheck the uuid (by sudo 
blkid) with the grub menu. (partly why I want the previous message to go 
first).

Also, I want to stress that using "search --no-floppy --xxxxxxxx" is far 
better than using (hdx,y)/vmlinuz-xx xxxx  or set root=(hdx,y) which was 
used by grub-legacy and is prone to errors as you have found out.

But, hope you got this sorted out and if all fails, "sudo grub-install 
/dev/sda"

Good luck - Goh Lip
