OK. Here's the deal:
The NVIDIA device needs two swaths of physical addresses to map on-card
resources into physical address space:
16 M non-prefetchable (likely register space)
256 M(!) prefetchable (likely video memory)
The CX23418 devices need one swath of physical addresses to map on-card
resources into physical memory:
64 M non-prefetchable (for both registers and memory)
Normally what happens is that when you add or remove a card, the BIOS
notices and recomutes where it should allocate resources for every PCI
device and stores it in the BIOS ESCD. Then when the Linux kernel
boots, it is free to ignore the BIOS' decisions and set up all the
resources itself.
Here's the problem: the BIOS or the Linux kernel is screwing up when the
HVR-1600 is installed an can't find a 265M, aligned, contiguous window
for the NVidia device's prefetchable memory and any other devies behind
the PCI-AGP bridge (of which there are none).
Notice from lspci or /proc/iomem, that when the NVidia allocations are
OK, the 256 M swath is located at e0000000-efffffff in physical address
space. When things fail it is not allocated. But look, at the PCI-AGP
bridge memory allocations when things fail:

A 256 M window is set up, but the BIOS or Linux has decided to align it on a
128 M boundary. This is essentially useless for a device behind this
bridge that has a 256 M window. From the PCI spec, the windows must be
naturally aligned by size.
And, to add insult to injury, if you look at the /proc/iomem for both
cases and the e820 data, a properly aligned 256M window should be
available at 0xd0000000-0xdfffffff.
So all that's nice, but what to do?
1. With the HVR-1600 installed, you could try:
a. unload the nvidia module(s)
b. manually fixup the PCI-AGP bridge and Nvidia device BARs
with setpci
c. reload the nvidia module
or
2. When you install both cards in the machine, enter the BIOS and clear
the ESCD data (it should be an option somewhere) to force the BIOS to
recompute things. Then when you boot linux make sure the kernel command
line has: pci=use_crs (or pci=use_crs,earlydump) to have the PCI current
resources extracted from the BIOS by the ACPI subsystem. (At least
that's what I think happens!) This will hopefully let you know whether
it's linux or the BIOS screwing things up.
or
3. When you install both cards, clear the ESCD data, and add pci=bfsort
to the kernel command line. This (or pci=nobfsort) should change the
order of PCI devices and may change the way linux allocates resources to
the devices.
Also the kernel commandline parameters: loglevel=7 and pci=earlydump
will dump alot about what the kernel is doing during early init and the
earlydump will dump out the PCI device config registers in the state the
BIOS left them in.
Good luck.
