battery and card reader of Acer ASPIRE one 532h - 2Db

Hi,

Recently I bought a netbook modelled as in the title,
and I use the default kernel, but there are 2 problems:

1. the battery life seems to be inaccurate...

2. the card reader doesn't work...

Is there anybody using the same netbook or having similar issues?
Please tell me how to deal with these problems.

Thank you very much!

I have an Aspire One D260. The battery level seems to be ok. But the Card Reader isn't working at all. When  insert a SD card, dmesg give me this:

usb 1-5: new high speed USB device using ehci_hcd and address 8

I tried to see if it was in /dev/sd* but there was only /dev/sda* so... I don't know what to do.

I have an N450, AFAIK the card reader uses a proprietary driver and isn't supported in linux.

I also have an Acer Laptop and problems with the card reader. When  I insert the card into the reader before booting then it is recognized

Same on an A110L. This in /etc/modprobe.d/modprobe.conf fixes it:

options pciehp pciehp_force=1

And put pciehp in the MODULES array in /etc/rc.conf

In my Aspire ONE D260, that way doesn't seem to work. Can anyone else report if it works in another AAO?

This doesn't work for my N450 but according to
this Ubuntu bug report
they've adapted the Linpus Moblin source code for the ENE cardreader driver and have it working.

**edit**

I just compiled the keucr driver and can confirm it works on my Acer Aspire One N450.
I downloaded keucr.tgz from the above page, extracted to ~/keucr then ran

cd keucr
make -C /lib/modules/`uname -r`/build M=`pwd`
make -C /usr/src/linux-2.6.35-ARCH M=`pwd` modules_install
insmod /lib/modules/2.6.35-ARCH/extra/keucr.ko

Works perfect.
