Well, for the record, IT WORKS!
Solution: A "via" chipset board. I got a "supercom" with both Slot 1 and
Socket 370 adapters.
Weakness: Can't probe my ultra-cheap Trident AGP card, chokes pre-post.
Advantage: Works with the wireless without any exceptional effort at all.

I don't mind back-accessable in this case. ;)

I've seen one in a product catalog. I thought it seemed crazy.

Uh-huh. But then I'll have to get new wireless, and this stuff is fine for me
for now.
