I belive the kernel MTD stuff has support for SPI flash, so you would 
just need to add a driver there for the EXI dma/pio stuffs, which is 
quite simple. referencing the us patent #6609977 should provide you with 
most of the info, as would referencing the gclib sources, though i don't 
remember what license the gclib sources are under...
adding a gc memcard fs should also be possible using the gclib sources, 
or re-reverse engineering the fs.
