I have the same problem neither of my card readers work on my A110l 9.10 remix. When I go to /etc/default/ there is no grub file. Are you saying that this file has to be created?

I had the same problem with my card reader and Ubuntu Netbook remix 9.10
beta, I solved like this: I modified /etc/default/grub on line

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”

and replace it for:

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash pciehp.pciehp_force=1″

after that I type:

sudo update-grub

and finally reboot, and works.

My netbook is an Acer Aspire One A150 with UNR 9.10 Beta with kernel
2.6.31-14-generic
