Doesn't Reiser4 do wear-leveling for flash?

We are using ext3 on a compact flash disk in an embedded device. So we
are not using RAID systems.
[I'm not subscribed, hopefully this threads]
Um, is this a new application or have you done this before?
It's my understanding that very few (or no) CF devices do wear-levelling internally.
Using a journal, especially a true data journal, seems like *the* way to wear out your
flash as quickly as possible.
If you've had success using ext2 in read/write mode on flash/CF in a shipping product,
I for one would like to know more details!
