The CF card just looks like an ATA disk to the OS, so
it should just run fine.  I have a bunch of ATA-to-CF
converters which I use for diskless applications, they
appear as /dev/ad0.

I also have an SBC (single-board-computer) with built-
in CF slot, it also appears as /dev/ad0 and works out
of the box.  (It has no disks and no fans, that's why
I use it as a stand-alone mp3 player built into a real
hifi case.  If you're interested, it's a PCM-5820 from
Advantech, see this URL:
They also have models with multiple NICs suitable as
diskless + fanless routers etc.

The main advantage of NetBSD in that area is that it
runs on many non-i386 processors, such as ARM, which
are very common in small embedded devices (and cheap
if ordered in large quantities).  However, there are
also i386-based ones, such as the Advantech ones, and
I don't see a reason why you shouldn't run DragonFly
on them.
