Ubuntu netbook SD card reader issue in Acer AspireOne

Recently I got a new netbook Acer AspireOne D255

Installed Ubuntu 10.10, unfortunately the new clutter windows manager - mutter was a big disappointment, it has an obvious performance issue when comparing without mutter even on a slower atom processor! this made me go back to 10.04.

The new model seem to be using a different brand of SD card reader which has no driver support from linux...
lsusb shows the following:

ENE Flash
UB6250
606569746801


After google around, several of suggested grub and modprobe config changes doesn't work at all, finally found the driver has just been recently added to the kernel from version 2.6.36, which 10.04 came with 2.6.32 obviously wouldn't work.

The new kernel isn't available in the standard repository, but to add it, just follow these simple steps:

sudo add-apt-repository ppa:kernel-ppa/ppa 
sudo apt-get update
apt-get install linux-image-2.6.37-8-generic

reboot with the new 2.6.37-8 kernel then you'll see the SD card!

Thanks for the info! However, when I do this it still doesn't seem to have the 2.6.37-8 kernel available. I am on a 64bit system though, so maybe this package is 32bit only? Maybe I'll break down and compile it myself later. Thanks for posting this info though, it seems to be just what I was looking for and it's good to know this kernel is the answer!

thanks for stopping by, it's kind of late to respond as I never checked the comments on my blog :-)
are you using a netbook? I didn't know there's a 64bit version for ubuntu netbook...
hope you have resolved the problem by now.
