Seems to work here:

# ls -l /dev/vcs[6789]
crw-rw---- 1 root tty 7, 6 Apr  1 22:21 /dev/vcs6
# cat /dev/tty7
^C
# cat /dev/tty9
^C
# ls -l /dev/vcs[6789]
crw-rw---- 1 root tty 7, 6 Apr  1 22:21 /dev/vcs6
crw-rw---- 1 root tty 7, 7 Apr  1 23:42 /dev/vcs7
crw-rw---- 1 root tty 7, 9 Apr  1 23:42 /dev/vcs9
# deallocvt 7
# ls -l /dev/vcs[6789]
crw-rw---- 1 root tty 7, 6 Apr  1 22:21 /dev/vcs6
crw-rw---- 1 root tty 7, 9 Apr  1 23:42 /dev/vcs9
# deallocvt 9
# ls -l /dev/vcs[6789]
crw-rw---- 1 root tty 7, 6 Apr  1 22:21 /dev/vcs6

Ah, nice.

If we figure out some dummy font-related call to check if the kernel
supports font handling at all, we could just add that to
vconsole-setup, I guess.
