In this case we are dealing with two bugs really.

1. The crash if you boot with a card

Maybe order of loaded modules?

Isn't the driver contained in your initrd? That is why blacklisting wouldn't
work. Please attach your initrd contents:
zcat /boot/initrd-`uname -r` |cpio -t

Could you output lsmod from init=/bin/bash and from normal boot to compare
which modules are innocent (are loaded from initrd) and suspected (loaded
later).
[you'll need to mount /proc again, it's read from /proc/modules]

2. The reader doesn't work if you boot without card

The PCI subsystem doesn't know about the device, so this is "expectable".
What's the problem here is why the device won't appear if he plugs the card in.

I guess this device (its bridge) is PCI-e hotpluggable. Could you post lspci
-vvxxxx from init=/bin/bash to see even pci-e extended conf space (card
inserted)?

Just in case, could you normally boot without the card, modprobe all of
/lib/modules/`uname -r`/kernel/drivers/pci/hotplug/*
and plug the card in? Does lspci contain the device?
