That was fixed in one of the first updates. That update has the u-boot on the eMMC check and see if there is a bootable SD card. If so, try and boot off of it. I've tested it, it works. That allowed me to add a physical partition for swap on my eMMC by booting off the SD card.
Before the u-boot update, eMMC takes boot priority and if there is something bootable on the eMMC, (even if the OS is broken), use the eMMC.
Note for others: If the eMMC is blank or does not have the SoC signature for the second stage boot code, then the SD card is tried next for booting. The problem that can happen is the the eMMC has something, (even if OS is broken, so it's booted first by SoC priorities.
I don't think that's what's happening, he already stated that he can boot ubuntu sd cards but can't get the wifi working when he does so.
I'm pretty sure something is fiddly with booting debian off an sd card while having a simultaneous debian install on the emmc, more than one person on IRC has mentioned that configuration not ever fully booting for them even after manually installing mrfixit's u-boot to the emmc.
