[bug#59003] [PATCH v2 6/6] installer: Report known-unsupported PCI devices.

[pelzflorian (Florian Pelz)]

Okay, the blame on the hardware manufacturer is fine as is.

I tested again by creating a dummy gpg key, locally adding it to
guix-authorizations and changing guix/channels.scm’s
%guix-channel-introduction.

Yes, this is fine, I think, even though AMD users will have also gotten
the uvesafb warning before and even though allegedly some AMD devices
work okay without firmware (except for 3d, according to h-node).

Also with the previous v1 patch revision (I had missed that), and now
testing on a PC with non-working AMD graphics, when I first select
shell-based install, I get the warning, then switch back to the
installer with Alt-F1 and select graphical installation, after first
seeing the uvesafb warning, the installer crashes.  installer-backtrace
is this:
