I suppose, your jMicron Cardreader needs a kernel module. Check (without card)
if it is loaded. If not, reboot with an inserted card, and check the
difference. Loaded kernelmoduels are shown with the command "lsmod".
If in second case, the module ios loaded, and in first case not, try the
following two solutiuons:
1. add the module in /etc/modules, reboot and try again.
if it does not help, then
2. build an own kernel and add the required module into the kernel (not as a
modul, build it directly into it), reboot, start the new kernel and try again.
3. Check your kernel version, I suggest to use 3.0

I suggest, not to use latest xserver-xorg for Nvidia-cards, there is a bug in
the latest version, but it appears only at special graphic chips (GF8600 for
example), try to use version 1.10.XXX.
Good luck!
