This maybe due to the change in 'pageStatus' byte (old yaffs1 
code) now being a (not)deleted bit in current code. If you want 
to shift between implementations and continue to use old data 
(format) try using the CONFIG_YAFFS_9BYTE_TAGS option in the 
current codebase (CVS). This enables a compatibility mode that 
formats the tags the 'old way'. You will also have to make sure 
MTD is doing it's part too, ECC layout etc., but you probably 
have that, else it wouldn't work as you describe.  See comments
in moduleconfig.h.

If I'm right, you may find that if you delete the files laid-down 
under 2.6 while mounted on your 2.4, you may see them reappear 
when you mount again under 2.6 -- I just guessing.

Please drop us of this version, the features added in this
tarball are now in CVS
