OK, tried it. Sort of works. I am still getting "shmem fs invalid option"
and mount is still complaining. Once the system boots if I do 'mount', there
is still no mounted /dev/shm. 'cat /proc/filesystems' shows shm is one of the
filesystems the kernel knows about. If I do 'mount /dev/shm' manually, it
works. Now I'm puzzled, but getting closer.
I was looking at /etc/init.d/devpts.sh. In the 2.2.x kernel docs, recommends
adding an appropriate line to /etc/fstab. However, Debian choose not to and
does it in a boot script instead; not sure why. I am tempted to hack together
a similar script for shm.

Which is apparently what is used to be. Looks like /dev/shm is the approved
mount point.

Which it did when I manually mounted it.

Not yet. :-) I'll have to try dbench and see how it compares.

*This* is *slow*?! :-) I didn't have chance to try the prerelease before
Linus released the real version
