Maybe you have a geometry mismatch between the CF card and the image
you wrote to it.

For comparison, I see this on a net4526 running 0.6.0+:

# df -k

This definitely looks like one of our net4526 images.  Suppose you dd
if=/dev/zero of=/dev/rwd0d bs=64k count=1 (careful, that *will* wreck the
boot record) and then run 'disklabel wd0'.  What numbers does disklabel
print for these fields?

bytes/sector: 512
sectors/track: 32
tracks/cylinder: 4
sectors/cylinder: 128
cylinders: 977
total sectors: 125056
