Well, I must confess, I don't use all those hibernate knobs that much,
but it can do lots of stuff:

$ ls /usr/share/hibernate/scriptlets.d/
acpi_sleep  	filesystems      	misclaunch      pcmcia
sysfs_power_state bootsplash  		grub             modules
programs         ususpend clock       hardware_tweaks  modules_gentoo
remount_xfsboot  vbetool devices     	lilo             network
services         xhacks diskcache   lock             newkernel
suspend2         xstatus fbsplash    lockfile         pause_audio
swsusp2_15

Some things can only be done in the binary that does the userspace
suspend; it can be the only user space program during freeze. I'm not
sure which generic things you mean...

Well, I should have worded it differently. I'm not saying that having
several distro's/projects reinventing the wheel is a great thing. It
would great if people could standardize on something. 
pm-utils surely has the ambition to become that standard script-suite,
and probably will come a long way because hal will depend on it, but
looking at cvs, it just seemed to be the next kid on the block. (I now
realize you're one of the authors and may have stepped on some toes;)

I just wanted to say that the state it is know in will have lots of
people loose functionality during hibernate.
