When I tried nandsim last week I used a small-page simulation, on
a 2.6.21-rc6 kernel/mtd (ARM) and I used the version of Yaffs I
have based on the code at
http://users.actrix.co.nz/manningc/yaffs2-ian-20070523.tgz

I have not used Yaffs with a large-page device (or sim) on a post
2.6.17 (when MTD API changed). You might like to read the
posting from Arvind Agrawal last friday:
http://balloonboard.org/lurker/message/20070629.213057.48c1691a.en.html
Arvind has identified an issue with MTD oob writing that looks
interesting -- this would also affect nandsim (large-page mode).
