a couple weeks ago, I sent mail to this list about using JFFS2 on a 
compact flash card, but haven't received any answer...

can anyone answer me, or point me to a document describing the procedure 
it it is at all doable ?

Probably because compact flash isn't really flash.  See the bottom of
linux-mtd.infradead.org

It's probably doable, but only via the blkmtd driver.  There have been
some recent discussions on this.  Take a look at the archives from last
week.

Hi,

I guess it depends on how the compact flash is presented. If it appears
to the system via a hard drive interface (?) then the answer would be
yes.

I'm running JFFS2 on USB Flash keys (which appear as SCSI devices
via /dev/sd??) via the MTD block device emulator .. the default read
speed is poor and the write speed is non-existent .. however if you grab
my patch for blkmtd.c posted earlier, I'm pretty much getting raw
read/write speeds from the key.
