Our code which should handle suspending erases to allow programming is
broken. So we disabled it -- you have to wait for erases to complete
before the code will write data to the flash instead.

That's odd. You have indeed done the correct things -- but writing to
the /dev/mtd2 device works, while jffs2 writes don't. I don't quite see
what's different. 

There have been some changes to the chip driver for AMD chips recently.
Out of interest, could you try an unpatched 2.6.8 kernel and see if that
behaves the same?
