Patching for broken SD card readers

I had the pleasure to buy a broken SD card reader. It reports 2GB cards as 1GB cards. Here is a fix that allows you to force capacities onto the scsi disk kernel subsystem of the Linux kernel: scsi-capacity-setter.patch. The respective user space program is here capacity.c. You might want to use it in conjunction with some udev rules.
