I though the rest of you might be interested in this, particularly since 
there's a major glitch that seems to have hit a bunch of people.

First, find a source that has the "yast-source" directory in it.  I used:

ftp.oregonstate.edu, who has 
"pub/suse/suse/i386/supplementary/KDE/update_for_9.0/yast-source/"

You want to point to the folder that has the "media.1" folder directly under 
it.

Becasue the mirrors are pretty heavily loaded, I mirrored the programs (not 
the source) to a local folder.  

Launch YaST, and choose Software/Change Source of Installation.  Click "Add" 
and fill in the relevant information.  You may have to mess around with 
whether to include the leading "pub", and whether to include a leading or 
trailing slash.  What's above worked for me.  When you get it right, you 
should see "adding installation source", which should take a while even for a 
local mirror.  If you get "unable to create...", try again and mess with the 
path a bit.  You should get errors within about thirty seconds, a successfull 
add over FTP will take several minutes - like five or ten.

Once you've added your source, make sure your original install source is 
enabled (and available).  Click close.  Now, from the YaST Control Center, 
choose "System Update".  If you have good original and new sources, you 
should see an "Installation Settings" page, one the most likely says 
"requiers manual intervention" under "Packages".  This should be the only 
item in red, otherwise something is not right.

You can accept the defaults here, or take some time customizing and trimming.  
Once you're satisfied with the package selections, and have passed dependency 
checks, you should be able to click Accpt, then Next.  One word of caution - 
there are conflicts with upgrading kdebase.  You must upgrade this package, 
so do whatever is required to fix this.  My first two systems both failed to 
upgrade kdebase, but I was able to simply go back to the "Install and Remove 
Software" application, search for "kdebase", and set the results to 
"Upgrade" (lightning bolt icon).  I'm working on my third system now, and 
I've been more careful resolving conflicts, but I've still had to go back and 
update kdebase manually.  There's also something still off, because 
KWeather's  "sun" is a green radio button.
