[Krzysztof Dłużyński <dlugaz@xxxxx>]

Christopher,
I have only tested video.use_bios_initial_backlight=0 because it was the first one and it actually worked nearly flawlessly (the only flaw was that I can lower brightness down till it turns off backlight completely). the hotkeys worked and I haven't noticed any lag when changing brightness. If you want I can check other workarounds if it is necessary. 
Best regards,
Krzysztof
