Actually, this has been a looong-standing problem. I have a series of patches to fix these issues, but it's more intensively involved with dma_*() functions.
The patches can be found in test/dma-fix branch of sound GIT tree. git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git test/dma-fix
This basically adds dma_mmap_coherent() function to feasible architectures, which is already implemented for ARM, so far.
thanks,
Takashi
