Firstly, and most importantly, CF - through a USB or any other interface - is 
not mtd capable, so mtd does not treat it in any way.

I have a Sandisk USB CF reader. Works great (ie. way better than with 
Windows). It uses the Mass Storage class driver. It needs SCSI/IDE configured 
and a few other things and appears as /dev/sda1.  There are various howtos on 
the www.
