Installed linux-lts54 for ndiswrapper, can't find encrypted partition.

I (rather foolishly) bought a laptop with the MediaTek7902 wifi/bluetooth chip. This does not have linux drivers.

I downloaded the windows drivers and installed ndiswrapper, as discussed here: https://wiki.archlinux.org/title/Networ … iswrapper/

This fails on

sudo dkms autoinstall

I have been informed this is due to changes in the linux kernel after lts-54. As such I installed linux-lts54 from the AUR.

I used mkinitcpio -p linux-lts54 to create a UKI, and used systemd-boot to attempt to boot it.
This failed.

and from /etc/mkinitcptio.conf:

HOOKS=(base microcode udev autodetect modconf kms keyboard keymap consolefont numlock block encrypt filesystems fsck)

I should say that both core/linux and extra/linux-lts boot perfectly fine, but dkms cannot install ndiswrapper.
I would be very grateful for any assistance or advice in getting linux-lts54 to boot, or indeed if you know of any way to get the system to use the MT7902 chip without resorting to linux-lts54.

Thanks!
