No relation. Also, we're in 2.6.26 development, most 2.6.15 bugs are entirely irrelevant.
The problem is PCIe hotplugging -- it doesn't work in Linux, at least, not with Expresscards. This issue is not specific to the HVR1500 -- you'll see it on other similar Expresscards as well.
Huh? We had expresscard hotplugging working in Linux before any other operating system ever did. It works for me just fine here on many machines, and does so for many thousands of users.

I can only get the HVR1500 / HVR1500Q / HVR1400 to come up properly if it is installed in the system when I boot up the PC. Inserting it after boot does absolutely nothing, and removing it after you booted the system with it installed will leave the system unstable.
Have you actually loaded the pci hotplug controller driver that is needed to get hotplugging of express cards to work properly? :)
Now I am very glad that I cc'd you.
I'll google a bit to find the name of the "pci hotplug controller driver" module, then give this a try.
Hopefully the solution is this simple.
Thanks Greg!
Regards,
Mike

This is what I see upon insertion of an HVR1500 with pciehp loaded:
