In the DECstation's case the DMA controller is the I/O ASIC. It's probably doable by writing a generic backend and various interfaces (see e.g. the 8390 driver), but much care must be taken. And one must work on the generic tree -- e.g. the Alan's one -- as otherwise changes will be impossible to test by most of people. > Well, I'll start off in merging in those two declance drivers.

Our driver really sucks: neither DMA (the I/O ASIC again) nor sychronous mode, just basic asynchronous support. I'm going to look at LANCE one day, too, but it's lower on the list. -- + Maciej W.
