Even if none of that ever makes it into the installer bugfixes, it would help anyone trying to install Debian on the CT60. Last I heard of someone attempting to use systemd on the CT60, it was too slow and continued to time out. That was 10 years or more ago, so some issues appear to have been fixed in the meantime. You'll likely hit the same timeouts due to slow crypto code again when using ssh - public key authentication (and the simplest crypto algorithms supported) was the only way for me. There used to be 060 optimized crypto libraries that could speed up logins a great deal, but AFAIR they used hand optimized assembly for crypto primitives. Not sure letting the compiler optimize for 060 can achieve near as much speedup. The keymap issue is a long standing problem - that should be reported to the installer team as a bugfix (same as the missing modules).
