  Oh, yes, and "Tekram DC395U/UW/F DC315U adapters" or "EISA AHA1742
 family" is very generic in our days, and "NE[12]000, SMC Ultra, 3c503,
 DS8390 cards" newtwork cards too, to name some random picks from
 GENERIC.

  Generic hardware in our days are CPU, ACPI, APIC, keyboard/console,
 AHCI, USB, HDA audio and Realtek 1G NIC. Period. Even Intel NICs
are not so generic (and even Intel itself solder Realtek on lot of their
motherboards).

  Servers? Ok, Marvell and Intel NICs + bunch (say, 3-4) SATA/SAS
 controllers. Again, no all these wide-SCSI and 10Mbit NICs.

  Hey, we still have "cpu I486_CPU" in i386 config! How THIS could be
 generic in 2012!?
