Why, then, did you not configure your new machine like the old one,
relying on the notes you made when installing the old one? ;-)
Why kernel 6.9? I just looked at $ eshowkw gentoo-sources, and there is
currently nothing there between 6.6.46 and 6.10.1.

Why have you built it with an initramfs? You only need such if you have
an encrypted root partition, or a /usr not on the root partition, or
something like that, that prevents the kernel booting normally. I've
never had an initramfs.

Sorry, can't help with any of that.

If you used GPM here for the mouse, possibly they're Ufffd characters,
i.e. ones which are outside the set of 256 which the console has been
configured for.

I'd tend to agree. Are you sure there's been change, rather than you
just finding your way into a different section of the maze of options
that characterizes insalling Gentoo? I'd certainly be interested, given
how I've ordered a new machine for myself and expect to be going through
the process in maybe a week's time.

There's nothing but point releases in the kernel, anyway. Going from
5.xx.yy to 6.1 just happend because Linus T felt it was time, not for
any specific new kernel features.
