[beagleboard] Are the 'modes' in the BBB documentation just history or what?

In the BBB System Reference Manual the P8 and P9 pinouts are documented with 7 modes for each pin which provide different uses for the pins. All of the actual software and descriptions I can find about the BBB hardware just talk about the Device Tree and Device Tree overlays. I have already

[beagleboard] Is it easy to reduce the clock frequency on Beaglebone I2C?

I want to stretch the I2C bus to a few metres, I will use screened cable to minimise noise pick-up but this will increase the capacitive load on the bus. So, I probably need to reduce the I2C clock frequency, how easy is it to do this? I will probably use the Adafruit libraries but don't have

I think I killed my BBB by injudicious prodding with a meter probe on connections to the power supplies on P9. All it does now when you power it up or press the power cycle button is to give a *very* brief flash on the power LED (the one by itself that is). Is it very dead or is it worth
