It may be feasible, but there is reason to disrecommend using a
journalled filesystem on flash, namely that journalling introduces a
"hot spot."

Whether it's ReiserFS or ext3, you introduce a ~32MB section of the
device that is being *continually* updated every time any changes are
made on the filesystem.

Flash devices can only cope with limited numbers of updates per
"sector", which means that you'll be diminishing the lifespan.
