Pardon my 2 cents from the peanut gallery. Considering that the
Raspberry Pi is currently selling at a rate of 700 per second (and
it's been on sale for a full week now), I would call that a mentally

You still can't run ARMv7 Thumb-2 code an an ARMv6t2 core. The same way you
can't run ARMv7 ARM code on an ARMv6 core. THe only ARMv6t2 implementation I
know of is the arm1156 (which I

*Debian*'s armhf is configured to use Thumb-2, but you could rebuild
the packages with a toolchain defaulting to ARM mode and your binaries
would be compatible
Wookey, thank you for the very detailed response.
