It should be possible to run Gentoo Linux too on anything that works with Linux kernel (although there was also Gentoo/*BSD projects in the past), as it's by default mostly manually built system (although I have [scripted install](https://github.com/kristapsk/gentoo-install)).

Likely he has more than one computer at home, including PPC and x86 Apple hardware, before ARM Mx chips.

You are correct. He seems to still be running Linux on a Silicon Mac to help improve the kernel for that CPU architecture. 

The last time I checked, Asahi Linux was the only Linux distribution that could run on a Silicon Mac, and it was in the experimental/alpha stage with many unresolved issues.

Here is a video made 2 months ago about the state of Asahi on an M1 Macbook Pro:

Maybe Linus uses more than one computer. Personally, I might run Asahi to experiment on it, but I would not use it as my daily driver at this stage.

Common, just google / duckduckgo "linus torwarlds apple", it's common knowledge. Started with PPC Macs, now it's Apple silicon ARM MacBooks.
