I didn't notice you were still having problems with version 1 of the
driver; I thought you had resolved that. IME that almost always means
your PCI config is not correct.

I have used a peek/poke utility to access the SYM53C8xx via PCI memory and
I/O. Both seem to be working fine. Obviously since the sym_2 driver works in
at least one configuration, the translation from the PCI bus back to CPU
memory is also correct.

Well, I would start by finding the error ("CACHE TEST FAILED: DMA error
(dstat=0x81)."), see under what conditions it occurs, and work backwards
from there.

It may really be that "normal IO" uses inb/outb. Do other drivers that
use ioremap/readb/writeb work on your system?

Still feels like an endian issue to me.

I'm not sure it is an endian problem because as I mentioned I've used
the sym2 driver on PPC without problems.
