[ydl-gen] Kernel hacking

[Sanders, Rob M.]

Double thanks Takashi,  I hadn't realized the change.  I think the kernel I'm using 
for the FC7 box is an older version.  I'll keep this in mind when heading back to YDL.

Thanks very much Takashi. That solved the problem and the kernel  
works fine (although, I can't tell the difference from the older  
kernel, except by typing "uname -r").

Thanks again.
