CF cards used in cameras and other consumer equipment almost always
mount as type vfat, so try that (and try fat if vfat doesn't work). 
But it's not a good sign that "auto" isn't working ... what you have
looks like it should work.  I haven't used the "sync" option, so
it's possible that's throwing it off.

Maybe try just (as root) mount -t vfat /dev/blah /path and see if
that works?  If it does, then you have a starting point to tune the
fstab entry.

The Zaurus community has a lot of trouble with large Sandisk MMC
cards -- apparently their timing is a bit different from most cards,
but I don't know if that's true of their CF and in any case
I wouldn't think it would apply to a linux machine reading
through a PCMCIA reader.
