Greetings.  Glad to hear it's still being useful.  (I idly wondered
whether anyone here would recognize me as such.)

Okay, I've added it to my TODO file. :-)

Using hardware snazziness just means using non-MI versions of more of
the drawing layer functions.  (Assuming suitable OS support, of course.)

I'm not sure it's because of a DMA channel.  I've seen it said that
black machines actually have blitter hardware, and knowing how to use
*that* would, I suspect, help far more.  I know using the hardware
acceleration of the cg6 immensely improved console feel on /sparc.

I'd love to get any doco you can release for the hardware.  (May not be
enough to actually help, but more information is almost never worse
than less information.)
