bug#65417: i686-linux installation medium on Pentium II fails on boot

[Skylar "The Cobra" Widulski]

I've got an old Pentium II machine that I want to install Guix on. 
Booting up the i686-linux installation medium, I'm dropped into a guile 
REPL with this output visible on the 640x480 rectangle because NeoMagic 
framebuffer seems unsupported:

It seems that there is an issue with the P6 (i686) microarchitecture 
used in the Pentium II, even though the image is labelled i686. I'm not 
sure what problem glibc would have with it.
Explanations? Possible solutions?
