I was almost ready to give up on this, due to the lack of time.... But you got me back on board
After I read your reply, I downloaded prodigy7's latest kernel archive. Before installing it, I pulled some data from the box running the stock kernel...
root@LS-WTGL70F:~# uname -a

...for future reference. Then, I unpacked the new kernel, and rebooted the box, and it came back to life after three reboots, in EM (and I'm not talking about EM2008
So I didn't change my /etc/linkstation_release, since I didn't know what to.
Bottom line is, I didn't get the custom kernel to run, but I'd appreciate any suggestions!
