You could consider using John Calixto's CMD passthrough ioctl for this,
and writing your tests in userspace:

  http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=cb87ea28ed9e75a41eb456bfcb547b4e6f10e750

It would be great to include your finished tool in a testsuite, both for
testing card commands and for testing the ioctl functionality itself.  :)

Thanks!

- Chris.
