From IRC: you should be able to boot the machine with the eMMC switched off, start U-Boot from an SD card and within 1-2s of starting flip the eMMC switch back on before the kernel starts detecting mmc devices. That should get you booted off the SD card and with the eMMC available for recovery/flashing.
Someone who's actually done this needs to provide further details if it doesn't work, I haven't had to recover from an unbootable eMMC this way. Apparently this method is safe as all the eMMC disable switch does is draw a clock signal low rather than cut power.
