I can't get lpt0 going.
I am running 2.0.5-ALPHA with a VESA local bus all-in-one controller 
board (hard disk, floppy disk, parralel port, serial ports).  I 
recompiled the kernel in order to get rid of the extraneous device 
drivers.  Here is the output from dmesg:

When, as root, I type the command   'cat /etc/printcap > /dev/lpt0' , I 
get the message "device busy".

The same hardware works with Linux and Dos. 

I would very much appreciate a pointer on how to proceed with 
trouble-shooting this problem.
