delaying or speeding up drm/kms with amdgpu driver?

I have a amdgpu, using the open source driver. amdgpu driver claims to do early kms by default, but the early is very late. Exactly 2.5s! I wouldn't care much but it breaks and delays my disk encryption password prompt. the laptop already boots with EFI video which is perfectly usable and correct. then DRM/KMS loads, and screw ups the size and fonts for the tty. Then sd-vconsole starts and corrects it. Hence I'm trying to either delay kms or force it to be *really* early. things that failed: 1. forcing edid

- # get-edid > myedid.bin
- do the dance to put file in initfs
- adding drm.edid_firmware=edid/myedid.bin to kernel parameters

it fails with "invalid firmware" but doesn't matter, i still get the error right on top of my sd-encrypt prompt, so it would not help move it early/later. 2. early kms hook. tried this weird mkinitcpio.conf list for the hooks

HOOKS=(systemd kms autodetect modconf keyboard sd-vconsole block sd-encrypt microcode lvm2 filesystems fsck)

still happens late. 3. forcing the right tty size/font thinking i can't win, i try to join kms and just tell it what to set things to when it comes crashing in. Added any combination of video=efifb fbcon=font:iso01-12x22 fbcon=nodefer video=eDP-1:1920x1200@60.03 (which is what sd-vconfig sets) it still ignores the font, and while it always set the display to the right resolution, the virtual resolution for the tty get's cut in 1/4 which breaks all the text for a while. And still starts at 2.5s into the boot. 4. bundling amdgpu firmware in initfs reading on https://forums.gentoo.org/viewtopic-p-8789979.html i added FILES=(/usr/lib/firmware/amdgpu/*) to mkinitcpio.conf nothing changes.
