Comment 19 for bug 292256

lspci -nn|grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation 82852/855GM Integrated Graphics Device [8086:3582] (rev 02)

sudo s2ram -i
This machine can be identified by:
    sys_vendor = "Samsung Electronics"
    sys_product = "SQ30"
    sys_version = "Revision 01"
    bios_version = "01LK"

I don't have a 98smart-kernel-video at /usr/lib/pm-utils/ but have one in /usr/lib/pm-utils/sleep.d , so i removed that.

Great news:
sudo pm-suspend --quirk-vbe-post
now works!
(in every case:
- from tty1 with kernel
- from X with kernel
- from tty1 with uswsusp
- from X with uswsusp)

:-)

Even the gnome power manager / suspend buttons of the laptop work now :-)

Thank you!
