[PATCH 2.6.23.9 001/001] parport: Added support for the Quatech SPPXP-100 Parallel port PCI ExpressCard

[Luís Mendes]

From: Luís P Mendes <luis.p.mendes@gmail.com>

Added pci device id for the Quatech SPPXP-100 ExpressCard - 0x278 - in include/linux/pci_ids.h
Modified drivers/parport/parport_pc.c to support the Quatech SPPXP-100 Parallel port PCI ExpressCard
Sucessfully compiled kernel modules against 2.6.23.9 vanilla kernel and tested the parport_pc module

This is a corrected version of the patch, the previous version had a problem, I didn't notice that the Quatech PCI vendor id
was already present in the pci_ids.h file, and that caused a lot of warnings.
I'm not affiliated in any way with Quatech or DPAC Technologies.
This card is a ECP+EPP PCI Parallel port with standard registers but at a different offset like many other PCI parallel ports, as such
the addition of this card required a small amount of modifications/code to get it to work under Linux.
