Gan,

I'm not sure about the WLAN driver for your module. But SDIO driver is certainly available in 2.6.32. Since the WLAN driver uses SDIO as a bus, SDIO bus driver and WLAN driver will be separate.

usually, when the board is power up, in mmc probe. will show "mmc2: new SDIO card at address 0001", but i cannot see that.

Yes, its required. Make sure that your card is connected properly or not. Also check for the card detect pin as well.

i think the problem is beacuse of mmc2 is not configured by MUX.
