If the issue is just keeping all the assorted GENERICs in sync, it's
probably easier to set up some kind of automatic cross-checking. E.g.,
one could write a cron job that extracts all the pci devices from each
GENERIC*, remembers the diffs among the lists, and mails out any
changes that appear.

I do think the size of configs is getting out of hand and some steps
should be taken to allow them to be more concise (not just GENERIC,
but also custom configs) -- but I think those steps are going to want
to be larger and more comprehensive than what's been proposed, and I
think it's important to take the time to work out exactly what configs
should be going forward. I rather doubt there's widespread agreement. :-/

Er, that would be less flexible, not more...
