Hi,

     Since you're using ks.cfg, I'll guess that your distro uses 
Anaconda.  
Install the anaconda and anaconda-runtime RPMs.  mount the CD and use cp
-a to copy the contents to your HDD.  Replace the RPM packages you find
there with the modified ones.  You speak of CD in the singular.  RH7 had
two.  If you only have one, cd to /usr/lib/anaconda-runtime type:
"./genhdlist <path_to_installation_tree>".  If you have two Cd's you'll
need to copy both of them to the HDD.  The genhdlist command would 
look like
this: "./genhdlist <path1> <path2> --withnumbers".  If you really want to
go all the way, and you're sure that the version of Anaconda is the same
for SME and RH7.0, you could download the Anaconda packages from the same
place you got the kernel packages.  They have the Speakup keymap built in.  
The buildinstall command in the /usr/lib/\anaconda-runtime directory will
make a completely new installation tree.  Since you use kickstart, this
might not be very important to you.  Now for the CD.  You can use the
strings command on the raw CD image to extract the commandline of the
mkisofs command that was used to create them.  Pipe to grep mkisofs.  
You'll want to edit out the version number such as 1.13.  If you have any
questions, call or write.

          HTH.
          Bill
