I'm making progress!  I'm using Linus kernel 2.6, have via82cxxx
and siimage built in, no scsi stuff at all, and set the ports and
irq's for ide0, ide1, ide2 and ide3 with Grub.  This makes the
siimage drives end up nicely as ide4 and ide5, or hdi and hdk.
It even allows me to have two network cards without crashing.

When the machine boots I always get a handful of "irq 12: nobody
cared", but most things seem to work fine anyway.  Except, of
course, that I now get corrupt files when reading or writing large
files.  It only seems to appear on the raid system, not the disks
themselves, so I'll check with the raid guys.

I'll try the -mm tree and see if it makes any difference.

Ok, that's the same as me.  Around 55MB/sec on the Via interface,
around 35MB/sec on the siimage interface, and 25-30MB/sec on the
Raid5 disk.  This is with just a Duron 800MHz, so that's cool.

Tons of thanks for all your help and your suggestions.
