Hi Paulo,
In most hibernate-scripts I've seen, a list of modules can be specified, which are loaded again after recovery. Such script is also handy to specify other things, such as immediately locking of the screen (e.g. 'xscreensaver-command -lock'), and unmounting network drives.
I use acpi with kernel 12.6.13.4 and have no such problem (suspend to memory and disk).

Rob de Graaf
