I have two laptops running Ubuntu Jaunty. Both have LVM encryption; one
also encrypts my home directory.

Suspend to ram works fine on both (had to correct a typo
in /usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm-asus.fdi to get the backlight to resume correctly

Hibernate, however, doesn't seem to work.

Note that leaving a laptop suspended to ram is less secure than a normal
shutdown if you have correctly encrypted the disk(s).
