This I have tried already, so I was in the right direction. I have read
the IO-mapping.txt, but when I use ioremap, the code does not compile
anymore. As soon as I include asm/io.h, I get several pages of warnings,
mentioning all kind of header files.
I have seen in the code of another driver that they use
-I/usr/src/linux/include in the Makefile. When I do that, it compiles OK,
but insmod tells unresolved symbol ioremap.
I think the way I make the code is wrong.

Use ioremap(physical_address)
Read /usr/src/linux/Documentation/IO-mapping.txt
Read other Linux PCI drivers code.
