Subjectdevices.txt errors
Major 216 was ttyUB%d (looks normal), but is now rfcomm%d instead?
The description claims that the device is a tty, yet it no longer
has a tty name?

Char major 204, the low-density serial ports, has some
sort of problem with the /dev/ttyCPM%d devices. Depending
on how I read things, there are 2, 4, or 6 of these.

Minors claimed: 46, 47
Minors available: 46, 47, 48, 49
Names claimed: 0, 1, 2, 3, 4, 5
The description: 0, 1, 2, 3, 4, 5

Here it is in context:

44 = /dev/ttyMM0 Marvell MPSC - port 0
45 = /dev/ttyMM1 Marvell MPSC - port 1
46 = /dev/ttyCPM0 PPC CPM (SCC or SMC) - port 0
...
47 = /dev/ttyCPM5 PPC CPM (SCC or SMC) - port 5
50 = /dev/ttyIOC0 Altix serial card
...
81 = /dev/ttyIOC31 Altix serial card
82 = /dev/ttyVR0 NEC VR4100 series SIU
83 = /dev/ttyVR1 NEC VR4100 series DSIU

Less serious:

Major 78 and major 112 claim the same name.

Some names, like "/dev/iseries/vtty%d", are too damn big.
Keeping things to "/dev/tty?????" would be appreciated.

Last I checked, ttyD%d didn't match the code.
