As I remember I tried kernel applied by this patch.
This was the first thing that I made after vanilla kernel.
I will try for sure again, but keep in mind that without DMA it is
horribly long.
Haha can you imagine what I felt when updatetedb for slocate was
runned at first time? Believe me I would like solve this problem as
soon as possible.
