Sure, and my oldest PC is running a *-686 kernel. So, the question
is, what's below the cutoff—what are we losing? On the Packages
page, my kernel is bottom of the heap, with the possible exception
of linux-image-5.10.0-13-686-unsigned (mine is signed).

Well, I have a "Intel® Pentium® M processor 1.50GHz". Unfortunately,
"M" does not exactly appear on either a "586←→686" scale, or a
"Pentium←→Pentium4" scale.
I know its cpu family is 6, and its flags are: fpu vme de pse tsc msr
mce cx8 sep mtrr pge mca cmov clflush dts acpi mmx fxsr sse sse2 ss
tm pbe bts est tm2. Worryingly, I don't see "pae", which has been
fussed about in the past.
Cheers,
David.
