I'm not sure I understand what you mean by concat for NAND. Do you mean being 
able to read/write directly to the char device?

Certainly handling OOB and pages makes things a bit different. Someone wrote 
a nand dumper which maybe does what you want (or can be persuaded :-). The 
yaffs format tool uses the char interface. It needs to expand to load up a 
mkyaffsimage image into flash.
