Subject: SDHCI driver runnining in aspire one, allows to write to R/O SD
 cards

Hi,

I am an owner of aspire one, and it has a card reader.
when I take a sd card, and pull down the protection tab, it still allows
to write to the card (I tested with my main notebook that indeed, it did
write there).

My main notebook, acer aspire 5720, doesn't have this problem.
Kernel version in use is 2.6.28 vanilla, but this did happen in former
version as well.

Attached lspci, on acer one.
