howto hibernate (suspend-to-disk) G4 PowerBook Titanium IV

[Lixus Zoran]

Hello,

I own a Titanium PowerBook with a G4 processor.
It runs Ubuntu dapper 6.06 LTS.
Suspend to RAM works fine with pbbuttonsd.

But I would like to have hibernate (suspend-to-disk) working.
But if I replace "suspend-to-ram" by "suspend-to-disk" in 
/etc/pbbuttonsd.conf and close the lid then it just blanks the screen,
even if X is not running.

I found a lot of approaches howto possible hibernate,

a) swsuspend http://suspend.sf.net 
b) Suspend2  (this only works on i368 ?)
c) pbbuttonsd ?
d) uswsusp 
e) pmdisk

but where should I put my effords in ?


TIA, Lixus
