No. That is repeating Kanoj's patch logic. What got into 2.4 kernel
is slightly different.

But like Stephen wondered, is there truly need to map the cards entirely
into KERNEL space at all ? It is fairly trivial to create mmap() driver
function to map them to user-space process.

In display drivers I can understand a need to map parts (control registers,
including command pipeline insert points) of the cards to kernel, but not
all of the buffer spaces -- at least not all the time.
