Typically, you wouldn't need to modify the Wombat drivers much, if at  
all.
However as you've probably seen from recent discussions on this list,  
we're
still working on getting DMA working on OKLinux (and we've been making  
good
progress), hence the Bluetooth and SD card drivers may not work  
perfectly yet.

Do you mean the NAND flash memory?  Chapter 6 of the s3c2410 datasheet  
might
be able to help you there.
