I suggest you do, it's more likely to work. I don't know about the PowerStack,
but at least on Macs legacy stuff doesn't work.

It's similar to a BIOS. Open Firmware uses it to initialize a card. Anyway,
I'd be surprised if an ISA card had an OF ROM...
Neither does the PCI card probably, so you might have to use the right
framebuffer device to use it. What graphics chip is on it?

The PC will use the BIOS on the card to initialize it.
