Issue #548 has been updated by Walter Sonius.
Works for me on X201, not sure if its the same ac-7260 adapter, have you tried
the other internal mini-PCIE?

Bug #548: Lenovo X201 Fails To Recognize Upgraded WiFi Card
https://ticket.coreboot.org/issues/548#change-1943
* Author: Jeremy Brown
* Status: New
* Priority: Normal
* Target version: none
* Start date: 2024-07-15
----------------------------------------
I am running coreboot 24.05 on my Lenovo X201.
I decided to upgrade my WiFi card from an Intel Centrino Advanced-N 6205 to an
Intel Wireless-AC 7260; since I selected the option to support Intel PCIe cards
in my build config I expected everything to work but my computer fails to
recognize the new card. The old card is still recognized if I reinstall it so I
know I didn't mess up the socket somehow; I've read reports of the 7260
[working with a modded factory
BIOS](https://richbits.rbarnes.org/installing-the-intel-7260-in-the-thinkpad-x201.html)
so I don't think there's an electrical issue. I've seen [somewhat related
bugs](https://ticket.coreboot.org/issues/311) but it seems their issue isn't
mine.
I've attached lspci data from both chips and my build config, lmk if additional
information is needed.
