BTW st SCC-XXdma stuff *is* enabled on my G3 by default.

 Beige or blue?  On my B&W G3 it's not enabled, I only see the plain
 non-DMA RX and TX interrupts.

 Beige - but I was burbling (again) - I build all my own kernels... so YMMV

FWIW:
With the same kernel...
On my Lombard - the SCC XXdma does *not* show
On my 9600 - it does.

So it looks like it's not getting enabled on New World machines.
After a brief look at the driver init code my impression (quite
possibly a wildly inaccurate one BTW) is that the driver wants DMA
channels and/or IRQs already partially configured.  On New World
machines booted via yaboot these may not be configured by OF.  On Old
World machines booted via BootX MacOS does the initialization.
