That's the case on every board because PCI-INT A is always shared with AGP
slot. Having shared IRQs should not be a problem at all but there will always
be crappy hardware and broken drivers.

I'd be surprised if your card shows up there:
$ lspci
[...]
01:00.0 VGA compatible controller: 3Dfx Interactive, Inc. Voodoo 3 (rev 01)
(prog-if 00 [VGA])
[...]
Flags: 66Mhz, fast devsel, IRQ 16
[...]
$ cat /proc/interrupts | grep 16
$
BTW: using IO-APIC and ACPI on modern systems may work better.
