Remove whitelist using only BIOS backup?

[clockworx]

I'm taking a look at my wife's Lenovo laptop, an Ideapad S205s (which is different than the S205 -Intel only for the S205s vs AMD only for the S205). The S205S was released on Sprint as a 3G-connected laptop, and as far as I can find there were never any BIOS updates released for it.

I did a backup using the Universal Bios Toolkit, which gave me a 4MB file. I then opened that file in PMTool, and was able to find the PCI IDs for the wireless card in one of the files.

From reading here though, it sounds like I'm completely out of luck without a manufacturer-released BIOS file to work with. Is that correct? I also removed the WWAN card and tried to put in the replacement card there, and while the OS recognizes the card I put in (Intel 5100), it doesn't find any networks to connect to, so there may be some other weirdness with it being put into the WWAN slot. The whitelist only triggers when replacing on the WLAN slot.
