Certainly not.
First, if the PCI probe reports that your PCI bridge is unsupported,
any and all PCI cards will be unsupported, too:
+----------+ + ----------+
| | VESA loc'bus | PCI | PCI bus
| CPU |-----------------| |----------------
| | | | | | bridge | | |
+----------+ | | | +-----------+ | |

VLB (or ISA) PCI cards
cards

accessible world fail not accessible!
You're much better using a true PCI board, which comes with a PCI ->
ISA bridge.
Btw., Jordan has been in error, the AHA 294X series is still not
supported.
