But this breaks existing...

Yes, this could be useful but for boot.cfg; but boot.cfg  is not
supported by all archs.

Hence the "grouping" proposal, that is independent from boot.cfg, and
that can have, IMO, a usage not limited to drmkms---a group being
defined so that the devices enabled/disabled by group can, indeed,
work or not imped the behavior of the kernel if disabled; I made
experiments disabling devices with pattern matching for drmkms,
ending disabling a child with the simple result that I painted myself
in a corner: there was no more display... So grouping is also
supposed to be "safe" variables definition.
