I agree the Voodoo 1 should work. The issue here is that I can compile in
tdfx character support for the kernel and still have it boot, but can't
boot with tdfx framebuffer support on the O2 for some reason. With just
character support lspci IDs the card

00:03.0 PCI VGA compatible controller: ...

However, trying to start X.org gives the following errors:

(EE) TDFX(0): V_BIOS address 0x0 out of range
(EE) end of block range 0x1ffffef < begin 0xfffffff0
(EE) end of block range 0xfef < begin 0xffffff0
