Yes and it is precisely because of bug https://bugs.maemo.org/show_bug.cgi?id=2747 Feel free to vote for it to have it fixed in Diablo. Also if you provide kernels for your project (Mer?,Ubuntu?) consider applying this patch to keep mmcblk device names consistent. It causes all sorts of confusion and unexpected side effects and may also cause reboot when removing card from device (at least Diablo works like this).
