In my /etc/mtab it says:

udev on /dev type tmpfs (rw,mode=0755)

You do the interpreting, please ;)

OK.

"udev" is the filesystem name.
It is accessable via the "/dev" naming prefix.
It is implemented using the "tmpfs" filesystem, kind of a fancy RAMDISK.
The filesystem is mounted "rw", or read/write mode, with the 0755
permissions.

Yup, it's a virtual filesystem. Nope, "tmpfs" doesn't understand
"noatime".

Well, ok, maybe I'll just use a combination of a slightly lower writeback
frequency specified in /proc/sys/vm/dirty_writeback_centisecs and all
non-/dev-filesystems mounted with 'noatime'. And perhaps it's no all that
bad to know when exactly a terminal received the last keypress, could
prove useful one day ;)
Thanks for your great help!
