I've been using suspend-to-RAM and suspend-to-DISK without problems with my
Compaq Presario 2203AL laptop with in-kernel suspend code. suspend2 doesn't
work for me at all. And I don't like their dictation or loading and
unloading modules. suspend1 does it without all that.
Some combinations that I use:
Boot kernel with acpi_sleep=s3_bios
Don't use DRM X modules.
That's it.
HTH,
