Trying to find a bootloader with mouse support

After much tinkering, and completely swapping the Bluetooth module, I was finally able to get the keyboard to work in Kubuntu on my Dell XPS M2010. The idea is a dual boot system with Windows XP for retro gaming and Kubuntu for anything requiring the internet, because XP. Unfortunately I have to re-pair the keyboard each time a switch between them. Not a huge deal but when I reboot after pairing with Kubuntu I lose keyboard support during POST.

I have found a few options; Grub Mouse (last updated in 2012), Gujin (last updated in 2013), and Burg. Burg appears to have a PPA for Ubuntu 19.04 but I can't find anything for 19.10. Does anyone have any experience with this? Is it still updated and compatible?
