This key and the DsSpooler keys are for publishing information
in active directory.  The lack of support for these keys should 
not affect the functionality of the driver itself (at least
i've never encountered a driver that did fail because of it).
I do have plans to look at this in the near future though.

Your problem actually sounds like a NULL devicemode.
Some driver swill not work without one (MSDN says a NULL device
is reason to reinstall the driver).  However to generate the 
device mode for a printer, you have to call an entry point into 
the drive's DLL (which we can't do natively).  That's why things
start working once you play with the printer properties.

Set the log level to 10 and look for messages about a NULL device
mode (`grep -i boing`) :-)
