Right, I think it’s only 3D that won’t work.  Maybe we should remove
them?  Dunno, we also want to warn about things that will not work to
its fullest.  Maybe we should reword the sentence?  Like:

  Unfortunately, it means those devices will not be usable.

  Unfortunately, it means those devices will not be usable or that some
  features will be unavailable.

WDYT?

Oops, thanks; I fixed that recursive call in ‘run-welcome-page’.

I also added a sentence under “Hardware Considerations” mentioning this
warning and pushed the whole thing, in the hope we can call for testing
real soon.

  514fedbf39 * installer: Report known-unsupported PCI devices.
  6b39c3afcc * installer: Error page width is parameterized.
  938d6161cb * installer: Use 'current-guix' for extensions.
  afbd4d8470 * linux-modules: Add 'load-pci-device-database'.
  655fb8feac * linux-modules: Add support for listing PCI devices.
  4f7ffb97a4 * installer: Warn about hardware support after the welcome page.

Thanks,
Ludo’.
