... Ah ;-)  So where do I find the APUS tree?  From digging around on
the web (man, there's a lot of broken links in the APUS faq ...), it
seems to be its own sourceforge project that hasn't switched to working
on 2.6 yet, is this correct?

Now that ncr53c8xx is non-PCI only, it should cause the absolute minimum
of wailing & gnashing of teeth to convert it to use the non-coherent
dma device API.  It would benefit PA-RISC too as we have two models
(735 and 755) that have NCR720 chips and a non-coherent architecture.
Right now, they use the 53c700 driver, but it'd be better to use the
ncr53c8xx driver, of course.

Are any APUS people interested in working on this?
