you aren't use fedora kernel. you have to patch kernel with some patches on bug #596475 if you want get this working.
BTW I just test it on my Dell E6410 , just works !
I have been using this for weeks on my 6410. It works really well.
Unfortunately not all have such luck. Particularly SDHC cards does not work:
Hmm. I am not really sure which SDHC cards are not working. I have a 4 GB card that registers as an SDHC card, and works properly. If you give me more information about what SDHC cards are not working, I will try to test them.

Does patch make device work?
Created attachment 479473 [details]
Modified version of adding ADMA quirk to e822.
Can someone test it?
Fedora-14 kernel build is here: http://koji.fedoraproject.org/koji/taskinfo?taskID=2846663
Things finally work fine with 2.6.38 on my E6410. I didn't have time to test patches recently, sorry.
Things work on 2.6.38 with patch from comment 6 or without patch?
Brice , could you please answer question from comment 8?
Sorry for the delay, it works with vanilla 2.6.38 without patch.
Ok thanks for the info.
I looked at the kernel mmc Changelog, and do not see which commit could fix the problem. Anyway since it fixed in 2.6.38, I'm closing bug since F-15 will use 2.6.38 kernel
