Luke,

I have a hunch that the geometry of the original image and the geometry
of the CF card are mismatched.

If you hold down Spacebar or some other "innocuous" key during boot,
you can get the bootloader to drop to the boot menu.  Then you can type
'boot hd0a:netbsd' to boot the system on the old partition.  Log in as
root (or su to root) and run 'disklabel wd0'.  Send us the output.

Also, send us the output of the Soekris BIOS during boot-up.
