Something tells me that can't be all the code.
0xcf8 is the PCI configuration address space, which Linux is almost certainly using.
What exactly is it doing or not doing?
Why are you attempting to get the parallel port I/O port? That's probably already in use, and there's far less drastic ways than writing a device driver to get to it.
Also, you have 6 posts under your belt, and surely have been told about code tags by now.

request_scroll
request_scroll(3alleg4) Allegro manual request_scroll(3alleg4)
NAME
request_scroll - Queues a hardware scroll request with triple buffering. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
int request_scroll(int x, int y);
DESCRIPTION
This function is used for triple buffering. It requests a hardware scroll to the specified position, but returns immediately rather than
waiting for a retrace. The scroll will then take place during the next vertical retrace, but you can carry on running other code in the
meantime and use the poll_scroll() routine to detect when the flip has actually taken place.
Triple buffering is only possible with certain drivers: you can look at the GFX_CAN_TRIPLE_BUFFER bit in the gfx_capabilities flag to see
if it will work with the current driver.
RETURN VALUE
This function returns zero on success, non-zero otherwise.
