Not at all. JFFS2 is designed to act on the real flash device, while
the CF hides it as IDE. The management of block lookup/erase/rewrite
is hidden in CF circuitry, you can't do that yourself.
> Is the CF card a "Disk On Chip Device" or a "Raw Flash"?
Neither. The former is a crappy device in a 24-pin package. It looks
like old EPROM devices, but with funny self-ads sticked on it.
The latter is exactly "raw flash", and nothing more. It's silicon
chips that are mapped in the CPU address space. nothing like that
exists in the x86 world, but it's pretty tipical in real computers :)

No.
/alessandro, waiting for some hints he asked to this same Peter Gerwinski :)
