The order in which the two are mounted is unknown to me (init scripts
of Debian 3.0), but I can confirm your tests. In my situation:

This is the situation:

debian:~# mount
/dev/hda3 on / type reiserfs (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
usbfs on /proc/bus/usb type usbfs (rw)
none on /dev type tmpfs (rw,size=15M,mode=0755)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
debian:~# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda3             8.2G  3.7G  4.5G  46% /
tmpfs                 443M   21M  423M   5% /dev/shm
none                   15M   12M  3.7M  76% /dev

As you can see /dev is 15MB big and /dev/shm is 443MB big. With this
situation, I've succeeded writing a file bigger than 15MB in /dev/shm.

In order to get DirectFB I only changed the size of /dev, the size of
/dev/shm was by default 443MB (50% of installed RAM?)
