I don't know - I haven't seen any information about these chips. It 
wouldn't surprise me. It's a shame it's 8 bytes not 4 - 4 would be fine for 
JFFS2. A page size of 8 bytes means you have to change the padding to 8 
bytes, or do the write-behind buffering that we're planning for NAND 
support anyway.
