While the Intel HW may not existing til 2006. A number of embedded SoC processors have had general purpose DMA engines on them for some time that these APIs may be useful for.

Memory copies in hardware Posted Dec 12, 2005 14:57 UTC (Mon) by alex (subscriber, #1355) [Link] Indeed, in a previous life I had to implement a generic DMA api for the SH4 family of processors for use by things like IDE controllers. I even implemented a user space interface for controlling DMA for user-space apps.
Memory copies in hardware Posted Dec 13, 2005 2:54 UTC (Tue) by jcm (subscriber, #18262) [Link] ppc4xx is one example - ppc4xx_dma is in need of a reworking anyway. I've recently discovered this in implementing DMA support for MTD devices - having a generic DMA engine API would also help here.
Side note: I love it when people start talking about amazingly cool technology that Intel apparently will revolutionise the world with, when it's been done for years and years already :-)
