What do you mean exactly? bttv's memory management code, which has
been copied to various places, and which is now broken in 2.5.x due
to virt_to_bus() being gone finally?

Some of this is work-in-progress. I'm talking to Dave to put some
helper functions to handle DMA to vmalloced memory blocks to some
sensible place within the kernel. If someone wants to have a look
(not final yet): http://bytesex.org/patches/15_pci-2.4.18-pre8.diff
