I'm trying to find the best non-AGP card fora Windows 98 machine. Any recommendations?
128mb of vram is way overkill for a 486. My first gen Pentium only has 24mb of system ram, and here you are trying to stick a gpu with 128 mb of vram into a 486? No wonder it didn't work.
Actually, most PCI video cards don't work in 486 PCI slots. The spec was new and the timing wasn't very tight in the very first PCI implementations. The OP is better off putting an ISA video card in his 486 for the least hassle.
It's more to do with later PCI cards using BIOSes which use Pentium specific assembly instructions. It's the same reason why a PCI card designed for x86 won't work in PowerPC or another architecture, the BIOS code can't run to init the card.
An example would be a Voodoo2 will work fine in a 486 because it's a memory mapped I/O device and doesn't have a BIOS, while a Voodoo3 doesn't work (in my experience) because it has a BIOS that requires Pentium class assembly instructions.

Prove it.
As someone who does not have the hardware to confirm this you better back up your claim with something more than a "No U".Prove it yourself.
The items to do the testing aren't that hard to get.
