Using a recent 3.10 version would be the most ideal solution as it
ostensibly includes fixes for heavy SD card access issues I was
seeing, the USB FIQ disable fix, and any other mainline issues people
were seeing since the 3.8 branch isn't really being maintained by the
Raspberry Pi foundation.  I believe it would need the patch that
Gilles and you figured out a few emails back.

The only problem is that I've never made a patch of that magnitude.
That said, I imagine it'd be similar to the 3.8 one that Paul made.
