two issues with suspend to disk in Suse 10.2

Hi,
I have a Samsung X20 notebook with Suse 10.2 installed and I use KDE.
I have a couple of problems I would like to solve.

1) I would like to have the option of suspending Linux and resuming
Windows and vice versa
without booting either OS (as it used to be with Suse 10.0). At the
moment the default for
Linux is the session from which the suspend is called. So it resumes
to Suse by default. How can I make Grub give me the choice I want? It
looks like (to me, a non-expert) in /etc/pm/hooks/99Zgrub Linux is set
as the default using grubonce.

2) If I have multiple sessions open, with the power button assigned to
suspend to disk in
each session, I have to resume twice. The first time the laptop begin
to resume and goes
back to sleep. The second time it resumes fine. With only one session
open, this doesn't
happen. Also when suspend is executed using "powersave -U" with two
sessions open,
this problem do nor arise. Therefore it looks like during button press
a suspend to disk is
evoked by each session, and is remembered and executed during the
first resume. The
same holds for suspend to ram. How can I fix this?

Thanks for all help,
Pramod
