No, I do not think so. The workaround being active does not cause any issues on boxes with updated firmware, so there is no point in trying to get the patch to older kernels. It is going forward that we want the "proper" behavior, when possible. Also, I am not quite sure when the new firmware version will get qualified for release. Thanks.

As Google/Intel will fix the BIOS/Coreboot issues with hardcoding virtual interrupt numbers for keyboard/touchpad/touchscreen controllers in ACPI tables, they will also update BOARD version number from 1.0 to 1.1. Let's limit the DMI quirks that try to preserve virtual IRQ numbers on Strago boards to those that still carry older BIOSes. Note that ideally not BOARD but BIOS version should have been updated. However the BIOS version used by Chrome devices has format of Google_BUILD.BRANCH.PATCH which is not well suited for DMI matching as we do not have "less than" match mode for DMI data.
