I have /tmp mounted on tmpfs and /var/tmp symlinked to it for two or three years
now, running KDE 3.5 on Gentoo almost every day. I did not have any problems so
far that I would associate with /var/tmp using tmpfs. YMMV
Didn't know about the fact that /var/tmp should preserve between reboots :-)
Also one could combine the preservation with tmpfs by copying the contents to
the harddisk and vice versa on startup / shutdown using inits scripts.
That's what I would do if I had the Firefox cache in tmpfs.
