Strange. It looks like you should be OK.
Some stupid questions:
Does the system have onboard video? (The Vintage2 AE-1 does. I mention it mainly because it has an A8V-MQ motherboard.)
If so, can you see a system boot with your monitor connected to the Geforce FX 5500 card?
In the BIOS setup, go to the Advanced Chipset Settings, AGP Bridge VIA K8M800 Configuration. Is the primary video set to AGP?
