I know my way to solve this problem is very strange but there are some reasons.
It is done for compatibility reasons (DMA and a strange architecture with custom gdt entries needed by the asm blob...)
In this application I don't need contiguous physical addresses so I will try the mmap fixed way.
I didn't only want to fork the driver but it is not a big problem...

will it be a large print work or there are another ways to do that? :)
