What do you mean by “support”? Flatpak is in the official repository and has been for a while.
You may also consider the backports repository for common software such as office and maybe your DE/tools.
Otherwise, I’ve used a T60 with Libreboot myself for years and it still worked fine for general purpose stuff, but then the CCFL display lighting went dead. It’s not TFT, unfortunately, so they don’t last as long.
