When you want to force booting from the SD card, you hold press the USER button (which effectively shorts P8_43 to GND). This changes the boot order to:
SPI
SD card
Sometimes (often?) the board fails to boot, possibly because it receives some stray signal on spi0_d0 or spi0_d1 (check the BBB's manual to see which one is expected to be used for iincoming data). Possibly, adding a pull down there could resolve this issue.
This is more of a documentation note than an actual feature request, as a resistor there may have negative effects on the bandwidth of the SPI bus.
