Getting MMC1 on the 'bone working...

Okay, I got a SSD breakout board from Sparkfun connected to the MMC1
pins in MODE 2 for the second card connector.

Do I need to patch a kernel and UBoot to get it recognized?

Kernel AND uboot, no. Patch the kernel, yes.

Okay, not as bad as I thought but still, ugh. Gotta trace the code then.

The latest kernel for the 'bone is still a patched 3.2?

Hmmm... Okay, FAQ time: Is the pin mux on the 'bone set at uBoot time
or when the kernel loads up?

Okay, not as bad as I thought but still, ugh. Gotta trace the code then.

The latest kernel for the 'bone is still a patched 3.2?

3.2.21 is the latest: GitHub - beagleboard/kernel at beaglebone-3.2

Great, I was using 3.2.0 from TI's repository. Time to switch, pull a
fresh vanilla 3.2.21 and these patches.
