Did you get the parallel port printer to work?  I have a MOSCHIP 9815 (2 
Parallel ports) going to /var/log and running "cat syslog | grep parport" 
yields

Apr 10 09:45:04 phenom kernel: parport_pc 00:0a: reported by Plug and Play 
ACPI
Apr 10 09:45:04 phenom kernel: parport0: PC-style at 0x378, irq 7 
[PCSPP,TRISTATE]

20, using FIFO [PCSPP,TRISTATE,COMPAT,ECP]

lspci -v yields

03:06.0 Communication controller: NetMos Technology PCI 9815 Multi-I/O 
Controller (rev 01)
        Subsystem: LSI Logic / Symbios Logic 2P0S (2 port parallel adaptor)
        Flags: medium devsel, IRQ 20
        I/O ports at cf00 [size=8]
        I/O ports at ce00 [size=8]
        I/O ports at cd00 [size=8]
        I/O ports at cc00 [size=8]
        I/O ports at cb00 [size=8]
        I/O ports at ca00 [size=16]
        Kernel modules: parport_pc

Doing a /sbin/modprobe parport_pc io=0x378,0xcf00 irq=7,20 runs but no 
printer is detected using any of the above ports.

The setup works in Windoz 7, same machine, so no hardware issue.  Running 
2010.2, PhenomIIx2 64 bit machine.  Any ideas.
