sudo cat /proc/ioports | grep parport returns only one set of addresses, (just to make sure)

Thank you very much for the tip!

With regards to the second port, you'll have to check how the second parallel port is enabled, some chipsets use strapping or use a eeprom for the config.
If you aren't getting the address of the second parallel port come up adding the connector and resistors may not enable it.
Find the data sheet first and work out how to config the chip first before getting out the soldering iron.

You are right!

I tried to read the registers with the remaning adresses and it didn't work.  



I tried both Base/Extended ccd8/cce0 and cce0/cce8. Didn't work. They must be strapped, as you said.
