Hello, I've tried your driver, and it worked fine at my laptop. I have a Samsung R70, with built-in SD card reader(in fact, it can read many cards, and there are 4 unknown devices related to it).The transfer speed with dd bs=512 is almost 800KB/s, which I think is fairly fast. I'm testing it with a transcend 2G mini SD card, with SD-miniSD adapter. I'm using 7-STABLE, so I changed kproc_create to kthread_create to compile the mmcsd module. There are errors, but the transfer completed normally.
