Here is the module compiled as part of power47, it works for me.
How exactly did you test this thing?

Anyway, i'm going to test this module later, these errors is annoying when downloading torrents on my n900.

Yes, I am keen to see if this driver (once debugged/tested) increases MMC performance.
I have a 16GB class 4, and when copying from the EMMC to the MicroSD, I would get very low average transfer speeds once the kernel's buffers were full. On the order of 200-400 kBps. Using the card for swap made my phone into a dog.

I renamed old module (as a backup), copied in the new one, rebooted, used a class 10 SD card that previously had problems, experienced no errors.

This is great, thanks.
This isnt a request just an idea...If the sd driver could be modified to unmount the mmc gracefully when the back cover was removed as opposed to just outright cutting the power. That be...sweet. Just think, if I remove the back cover while my swap was mounted on the SD card it would nicely unmount swap as opposed to rudely cutting it of, the machine spazzing out then dieing.
Obviously if you're using it for swap, it is always in use, and that's always going to result in catastrophic failure.
I think one solution is to create your own "unmount SD card" script, make a Queen Beecon widget on your desktop or something to call it when you want to remove your cover. It would need to alert you if any partitions cannot be unmounted for any reason, that way you know it is not safe to remove the back cover.
Even better yet, glue a magnet onto the sensor so your N900 thinks the cover is always on.

after reflash i think you should install multiboot to get rid of such reboot loops in future (correct me if I'm wrong)

. The irony is that I haven't installed multiboot yet because I wanted to get my MircoSD card working before installing multiple OSs. Time to reflash I guess. It looks like I followed the same procedure you did to test it. I also made sure that the patched kernel module file permissions and ownership matched the original one.

I think when you replace the default kernel you will get the reboot loop problem. So, just replace for power kernel.
I´ve tested here, all good so far. Thank you!!!

Or EVEN better, the driver would emit a dbus signal so I could run a script when the back cover was removed and nicely swap the swap elsewhere, beep/vibrate when it is done. Bleep nastily if I opened the back with the sd card mounted.
You get what I mean?
