Trouble loading kernel module spi_pxa2xx_platform

I am having trouble with the aur package macbook12-spi-driver-dkms.
Working on a macbook12, Early 2016 model. My kernel parameters include "nomodest" and do not include "noapci", as noted here.
I have also created /etc/modules-load.d/intel_lpss_pci.conf

# Load intel_lpss_pci at boot
intel_lpss_pci

and /etc/modules-load.d/spi_pxa2xx_platform.conf

# Load spi_pxa2xx_platform at boot
spi_pxa2xx_platform

Furthermore, I have edited /etc/mkinitcpio.conf to enclude

MODULES="intel_lpss_pci spi_pxa2xx_platform"

I believe I have done something wrong as, the output of #hwdetect --show-modules is

AGP      : intel-gtt
ACPI     : button video
BLOCK    : scsi_mod sd_mod usb-common usbcore xhci-hcd xhci-pci uas usb-storage nvme-core nvme

As you can see,  intel-lpss-pci is loaded, but spi_pxa2xx_platform is not.
Thoughts?

Re: Trouble loading kernel module spi_pxa2xx_platform

Try to load it at runtime and check dmesg/journal for related error messages?
Also rebuild the module and watch out for errors.

Finally I don't know what "nomodest" does, but if it's a typo for "nomodeset", that's gonna kill your GUI support.
"noapci" probably does nothing, "noacpi" would break https://en.wikipedia.org/wiki/Advanced_ … _Interface but the page actually ensures to not use "noapic" - this: https://en.wikipedia.org/wiki/Advanced_ … Controller

tl;dr - spelling matters, so ensure you got no local typos ;-)
