Nothing in the rtl8192se driver changes the PCI ID. That information is hard
coded into the device. I do not know why the Thinkpad's BIOS did not flag the
card as illegal on the initial startup. My HP certainly does.
I think that "whitelisting" the wifi cards is a horrible practice. I have used
HP notebook computers for about 10 years, but the current one will be the last
due to their BIOS practices. I own 14 mini-PCIe wifi devices, and only 2 are
whitelisted. Similarly, I will never buy a Lenovo notebook. I use these
"foreign" PCIe cards on an ExpressCard extender card, but that came from Realtek
as part of my work with them. I do not know of a source for these cards.
