The answer is "yes, but you don't want to go there." I've used a weird
version of mtools in the past - written by an ex-cow-orker of Jim's,
interestingly enough - to read the SD card which was inserted into a
floppy-shaped holder. It was painful, slow, ugly, and problematic (I
could write a novel), but it let me have a Linux-only laptop. SCSI
emulation was a *lovely* release from that method; given "hotplug", I
just connect the camera to the USB port, and my "/mnt/sdcard" contains
all my pics.

/dev/sdb   /mnt/sdcard   msdos   user,noauto,gid=103,fmask=113     0  0

Works a treat.
