Hi Eric,
Yes I'm aware of the ISA DMA 16MB limitation and will try to duplicate
whatever "bounce buffer" code I find in either st.c or sd.c into ss.c.
The SunOS version of the PINT scanner driver uses only 63KB of buffer
space and moves data from a scanner at a fair clip so I imagine I
shouldn't need too much buffer space for the Linux PINT.

Nope, NetBSD just ignores this problem(!) and I have no copies of
FreeBSD, SCO, etc.
