You were right, wrong kernel (had named it zImage instead of zImage.bin... silly Zaurus owner!).
Reflashing now (and SO NICE not to see the SHARP logo filling the screen--nothing against Sharp, but I couldn't read any boot messages!).
One bit of "human interface" stuff. I've gotten to the questions about "I found a .backup, do you want me to restore?" and answered no.
The next question is confusing: "Do you want me to delete your settings? If you upgraded from Sharp rom, this is required". Well, I *do* want to delete my settings then. But the prompt is actually "enter OK to restore your backups". So the answer to one question is "yes", but you really want to type "no" I think, and I have to admit that is confusing to me. Maybe changing the wording there would be a touch more clear.
Works great, and having the right kernel fixed my Buffalo problem of course. Thanks again!
