I'm using a similar 128MB device with no problems on a Fujitsu/Siemens
E6646 Lifebook (an x86 laptop) under 3.3-stable.

I don't think I ever managed to mount it (I didn't have a proper disk
label), but I didn't try very hard, because mtools (available as a
package or via ports) accesses it just fine (I have a messy-dos file
system on it).

Relevant parts of my dmesg:

When I plug it into one of the USB ports, I get a console & dmesg
message like this:

umass0 at uhub0 port 1 configuration 1 interface 0
umass0: vendor 0x0c45 USB Mass Storage Device, rev 1.10/1.00, addr 2

I'm accessing this as the u: drive in mtools.  My /etc/mtools.conf 
looks like this:

# usb flash drive (left slot on osmium)
MTOOLS_DATE_STRING="yyyy-mm-dd"
drive u:
  file="/dev/rsd0c"
  mformat_only
  cylinders=125
  heads=64
  sectors=32
drive a:
  file="/dev/rfd0Bc"
  mformat_only
  cylinders=80
  heads=2
  sectors=18

ciao,
