: I had the same concerns too, but was not able to come up with anything
: better. BTW, I think those devices were the first that ended with a
: digit.

No.  They weren't.  There are sound devices that end in digits:

# snd_ad1816:           Analog Devices AD1816 ISA PnP/non-PnP.
# snd_als4000:          Avance Logic ALS4000 PCI.
# snd_cs4281:           Crystal Semiconductor CS4281 PCI.
# snd_ds1:              Yamaha DS-1 PCI.
# snd_emu10k1:          Creative EMU10K1 PCI and EMU10K2 (Audigy) PCI.
# snd_envy24:           VIA Envy24 and compatible, needs snd_spicds.
# snd_fm801:            Forte Media FM801 PCI.
# snd_maestro3:         ESS Technology Maestro-3/Allegro PCI.
# snd_sb16:             Creative SoundBlaster16, to be used in
# snd_sb8:              Creative SoundBlaster (pre-16), to be used in
# snd_via8233:          VIA VT8233x PCI.
# snd_via82c686:        VIA VT82C686A PCI.

but since they all live on an enumerated bus, they all share the name
"pcm".

There are also these:

device  tnt4882                 Nat Ins PCI GPIB card
(which does have the digit in the name:
static driver_t pci_gpib_driver = {
        "tnt4882",
        tnt4882_methods,
        sizeof(struct tnt_softc)
};
)

and the following which are just config options:

#device         ath_ar5210      # AR5210 chips
#device         ath_ar5211      # AR5211 chips
#device         ath_ar5212      # AR5212 chips
#device         ath_rf2413
#device         ath_rf2417
#device         ath_rf2425
#device         ath_rf5111
#device         ath_rf5112
#device         ath_rf5413
#device         ath_ar5416      # AR5416 chips

Interestingly, drm avoids this by:

device          drm             # DRM core module required by DRM drivers
device          i915drm         # Intel i830 through i915
device          mach64drm       # ATI Rage Pro, Rage Mobility P/M, Rage XL
device          mgadrm          # AGP Matrox G200, G400, G450, G550
device          r128drm         # ATI Rage 128

I've also been at companies (well one) that have device names that end
in digits.
