this is very much NOT true. if you take the source the provide you can

If we are opining whether Tivo provided complete source code for their
Linux kernel images, the requirement to change non-GPLed software as a
condition to exercise GPL-protected rights speaks for itself.
no, the GPL protected rights don't say anything about the hardware the
system runs on.
you are saying that the GPL now controls what the BIOS software is allowed
to do or not allowed to do.
that's a seperate body of code that is in no way derived from the linux
kernel (even the anti-tampering functions would work equally well with
other Operating systems and are in no way linux specific). it's no even
loaded on the same media (the BIOS is in flash/rom on the botherboard, the
OS is on the hard drive)
and note that the software that is checked to make sure that it hasn't
been changed includes much more then the kernel. it checks the kernel and
the initrd.
Out of curiosity, what do you have to do on models besides those? Are
newer models more or less restrictive in what they run? If newer
models are more restrictive, I think that also speaks to whether Tivo
thinks it is conveying complete source code.
newer models do tend to be more restrictive, but they also tend to connect
to more propriatary networks (satellite or cable)
