The title of this thread is still relevant so I'll just update.  After 
another failure with the media_build script, and also with rpmbuild 
-rebuild with the ATrpms SRPM (with just the current sl6 kernel and no 
attempt to update the specfile)  I tried the 'kernel-lt' from elrepo. 
The PCTV-290e works in 0.26-fixes under that - after a second reboot.
