Comment 24 for bug 424877

Well, the the pciehp module was removed in jaunty, but pciehp.pciehp_force=1 for some magical reason still works, see bug 271019 (this fixes the weird behavior of the SD card slots).
I'm really sorry to hear that this workaround doesn't work for you guys.
Just a shot in the wild: could anyone try to see what happens if you disable '/apps/nautilus/preferences/media_automount_open' in gconf-editor?
This is the only other tweak I did on my system.
