A few more searches, now that I've trimmed down the Trixie wishlist a
little, seem to indicate the Mediatek MT7925 WiFi 7/BT Adapter might
be an option. I'm seeing it packaged as a mini-PCIe module, which is
something I'm quite familiar with (got a bunch of adapters to USB,
usually for modems).

It would seem to be supported by linux.git as of v6.12:

    drivers/net/wireless/mediatek/mt76/mt7925

and even the firmware file mentioned in the BT stack seems to be
available:

    drivers/bluetooth/btmtk.h:#define FIRMWARE_MT7925               "mediatek/mt7925/BT_RAM_CODE_MT7925_1_1_hdr.bin"

    → firmware-mediatek: /usr/lib/firmware/mediatek/mt7925/BT_RAM_CODE_MT7925_1_1_hdr.bin

Regarding the wireless stack, those firmware defines are used in
MODULE_FIRMWARE() calls:

    #define MT7925_FIRMWARE_WM  "mediatek/mt7925/WIFI_RAM_CODE_MT7925_1_1.bin"
    #define MT7925_ROM_PATCH    "mediatek/mt7925/WIFI_MT7925_PATCH_MCU_1_1_hdr.bin"

    → firmware-mediatek: /usr/lib/firmware/mediatek/mt7925/WIFI_RAM_CODE_MT7925_1_1.bin
    → firmware-mediatek: /usr/lib/firmware/mediatek/mt7925/WIFI_MT7925_PATCH_MCU_1_1_hdr.bin


I'm still more than happy to take any recommendation regarding Wi-Fi
7 chips, even more so if people have actually confirmed being able
to use them, e.g. on a Debian system installed in some other way
(Ethernet, USB/Ethernet adapters), or from a Debian Live system.

Ideally I'd love to have something like 2 to 4 different chips, just
in case some of them are easy/easier to work with than others…

Feel free to relay this query as widely as possible. I can be
reached via the Fediverse as well: https://mamot.fr/@CyrilBrulebois

Thanks, everyone!
