Sadly I have no TV. :)

Anyway, I think it would be interesting to learn about arch-specific
bugs discovered with trinity. Quickly thinking, the results should be
mostly same regardless of the architecture since the code being tested
is generic especially when running as a regular user. But of course
there are 32/64-bit and big-endian/little-endian and such differences,
and maybe some permission bugs (likely in vendor kernels).
