- Under all circumstances, you will need to change the driver code so
- the clock divisor is set according to the new speed. Besides that,
- there is no guarantee that it will actually work - since you don't
- know if the dma between the 33c93 and the DMAC will work.
-
- I was looking at this some time ago, but newer finished it as I had
- some problems getting hold of the chip (20MHz). I haven't resigned yet
- though, just don't know when I'll find the time :-)
