uboot and ext to nand

Paul
Hi there,
I ve long been using the sd card as a storage device on my mini2440, but
lately I ve been looking at some high-speed stuff, so the nand is appealing
once again!
Does anyone know how to move the ext image created by openembedded over to
the nand?
I know how to move the jffs2, but when it decompresses it spits out tons of
errors.
Is there any way of putting a non-compressed fs on nand?
Thanks
Paul
