Hi Ohad,
                   For 2.6.32, some more SDIO stuff needs to be backported. For example, I get the following error:

[   16.232482] mmc1: card claims to support voltages below the defined range. These will be ignored.
[   16.241424] mmc1: host doesn't support card's voltages
[   16.246643] mmc1: error -22 whilst initialising SDIO card


So, the part for handling reporting card voltages need to be added in.

Also the SDIO run-time PM patches are not nearly as easy to apply to the android-rowboat-eclair-2.6.32 kernel.

Is the SDIO subsystem sufficiently modular so as to allow me to take a few file and use it as a drop in 
replacement for the 2.6.32 kernel?
