You probably don't want the (new) option CONFIG_YAFFS_9BYTE_TAGS
turned on, do you?  This option was on by default when Charles 
merged the "9 byte tags" support on July 18th.  This was fixed 
in moduleconfig.h revision 1.7 2007-07-23 19:10:11, where it
is now off by default.

This may not have anything to do with your bad-block markings.
I recommend you disable bad-block marking by hacking MTD
while you get Yaffs working.

To check if the Yaffs/MTD setup is working for your particular 
Yaffs/MTD versions, try running Yaffs with MTD's nandsim.  After 
you populate the Yaffs fs with some test files, you can unmount 
and remount the fs to see if Yaffs can reconstruct the fs from 
the nand(sim) data, and you and compare the files.  This should 
give you/us some confidence that your Yaffs/MTD config/api is 
workable.
