Edit - added 'lspci -kk' output

I have installed Gentoo on a shiny new Dell Precision 7730. I cannot seem to get the touchpad to drive in xorg. This seems to be a regular (and solvable) problem with Dell laptops, but so far each of the remedies I find via Google have had little effect. Here are some details:

Code:
# cat /proc/cmdline.txt
BOOT_IMAGE=/kernel-genkernel-x86_64-4.18.9-gentoo root=/dev/mapper/vg0-root ro nvme_load=YES dolvm crypt_root=UUID=c02f4769-e093-4693-9259-bbd8d197457c root=/dev/mapper/vg0-root i8042.nopnp



It should be noted that before I added i8042.nopnp, there was *NO* pointer device of any type showing up in xinput or /proc/bus/input/devices... no touchpad, stick, PS2 mouse, nothing. Adding i8042.nopnp caused the "PS/2 Generic Mouse" to show up, which I think is still wrong. But at least it was a change.

Does anyone know how to make a Dell touchpad work?

Code:
CONFIG_I2C_DESIGNWARE_CORE=m
CONFIG_I2C_DESIGNWARE_PLATFORM=m
CONFIG_I2C_DESIGNWARE_PCI=m
CONFIG_I2C_DESIGNWARE_BAYTRAIL=Y
