It should be fairly easy to read read the public key from the Certicom
root.
It uses a named curve which can be obtained from the parameters field
which is an OID: so you'd need an OID to curve table.
The actual public key value should be a case of decompressing the public
key value, shouldn't be too hard if you've got some basic operations for
2^m EC.
If you need any hints of how to do that let me know.
