Hmmm..... how did you solve the problem that you need 5 control signals 
(4 enable, 1 strobe) but have only 4 (either the four "real" control 
signals or DB4..DB7?

I know that theoretically we could use up to eight control lines (high 
data lines + control lines), but that would require some heavy 
modifications to the parport abstraction layer

Could you please provide a "real" patch (a context diff)?
