I'm working on the Amd's and Fujitsu too.

FYI, I have buffered writes implemented here and working already.
This gives a write boost of about 14x to 16x!
Testing was done on a PPC405 board equipped with Am29LV128MH,
using patched Denx Linux.
Let me know if this is of any interest for you.
I'm waiting for the 2 following patches to be commited before I submit
what I've done.
Stefano's patch on "erase/write on the same AMD chip with not aligned words"
My patch on oops fixup
PS: sorry, my mailer suck and it's missing the Ref header.
