Alexei, make sure you have :
1) CONFIG_SHMEM=y and CONFIG_TMPFS=y in your kernel's .config file
If not, run "make menuconfig" and enable it in File Systems -> Pseudo
filesystems -> Virtual memory file system support (former shm fs)
2) you should also have "none /dev/shm tmpfs defaults 0 0" in your fstab
Both of which are standard defaults on Gentoo.
