| rebooting into kernel-3.15 the system halted with "Kernel panic -- not
| syncing: No init found." I've rebooted into the slightly older kernel

Actually, that's very strange -- I just tried the SD card reader
again, on a lark, and the SD card is now mounted and readable! Yet
this is the same kernel version as I had originally, and lspci still
not apparently doesn't recognize the card reader:

$ mount | \grep mmc
/dev/mmcblk0p1 on /media/jbednar/CANON_DC type vfat (rw,nosuid,nodev,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks2)
$ lspci | \grep Realtek
02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5227 PCI Express Card Reader (rev 01)
$ uname -a
Linux novo 3.13.0-29-generic #53-Ubuntu SMP Wed Jun 4 21:00:20 UTC
2014 x86_64 x86_64 x86_64 GNU/Linux

I have no explanation.
