Thats primarily about resource handling orders. Making sure we don't release the claimed pci resources in the driver until the driver itself is sure it has shut up.
I'm doing suprise removal ok with the thinkpad 600 (in 2.4 with some limits due to the 2.4 pci layer). Network stuff seems to be fine. The block layer has major issues.
