Upgraded to 14 last year with no issues, but recent pkg upgrades breaks brightness buttons on ASUS UX461(F).

Code: 
kbl_dmc_ver1_04.bin: could not load firmware image, error 2

i915_kbl_dmc_ver1_04.bin: could not load firmware image, error 2

Keyboard backlight buttons are working but:

Code: 
ACPI Error: Aborting method \134_SB.PCI0.LPCB.EC0.SLKB due to previous error (AE_AML_BUFFER_LIMIT) (20221020/psparse-689)

ACPI Error: Aborting method \134_SB.ATKD.WMNB due to previous error (AE_AML_BUFFER_LIMIT) (20221020/psparse-689)

FreeBSD 14.0-RELEASE-p3
 
Tried with all asus drivers, everything is loaded after the boot (including i915kms) and kld_load confirms, kb light and sleep buttons are working along with leds but still can’t change the display brightness. `lcd0.brightness` in sysctl is ignored
 
This really bothered me for a while, so I just got a chance to revisit. Decided to try with the current pkgs (recent bump) before digging into the drm changelogs, so I installed 510 and dropped drm-kmod/515 — still same errors, BUT brightness keys are now functioning again. No issues with other keys (besides the old errors above); it looks like this one is closed.
