Surely it does support LVM, but it's not build in the kernel itself. 
Instead, the initrd (INITial Ram Disk) is used, which carries the kernel 
modules (see them as "drivers") that are needed to continue booting, 
mount the "/" FS (where the rest of the modules resides), etc.
http://en.wikipedia.org/wiki/Initrd

Usually, the initrd is not distributed as a binary, instead it is build 
directly on the target system, to make sure it includes everything it 
needs, and omit everything it does not need. It's a rather automatic 
process, so I would expect that if you just "force rebuild" your initrd, 
it will put everything in place.
Good idea to do that from a chroot environment, after booting your 
system from your distribution LiveCD. I'm not familiar with Suse at all, 
but I'm sure it's documentation describes this process.

Definitely "/" can reside on a LVM volume, it's a fairly common setup. 
If your other HVM system is similar to the one you are trying to get 
work, you may try to copy it's initrd to your "XVM69" machine. That 
would be dirty, but simple, in case you don't get your system booting by 
other means and re-build it's initrd natively.
I have seen the mail you sent me.
The path of the kernel and inird are relevant only on the boot loader 
stage. If you get past that point, you may conider you have a working 
configuration of that component.
The boot from a LiveCD is the way I suggest to fix your booting. Once it 
works, your regular configuration shall become boot="c".

As a separate matter, please consider using some standard way to quote 
the sender's messages, otherwise your replay is difficult to read (even 
difficult to find). Allow me to suggest you some reference:
