The problem the OP is not that the CF device itself is not detected - the device being /dev/da1 - but that the partition on the device (da1s1) is not detected. It is possibly malformed. The OP should nuke the device (overwrite with dd if=/dev/zero of=/dev/da1 bs=1m), re-create the partition table and see if that helps.
