It's not so private [1], but isn't working yet :-). I'm still new to the whole 
kernel development stuff and seem to be the only one working on this device 
family.

I know from comparing s3c2416 and s3c64xx manuals that the hsspi part is the 
same but still have some learning to do to get it to work and also need 
drivers for the other side of the spi connection.

The Asus eeeReader DR-900 uses a wlan chip supported by libertas. So having a 
"verified" driver on the other side might help me in getting the spi driver to 
work.
