After more investigation using 2.6.26-rc9:
I could suspend and resume using acpi-support's legacy mode. The trick
is to shutdown alsa (which acpi-support legacy mode does), and then
add the following modules to the exclude list: snd_intel8x0
snd_ac97_codec
It should probably be investigated whether those modules should be added
in some blacklist in acpi-support (I haven't tested whether snd_intel8x0
or snd_ac97_codec is at fault). (that's why I'm reassigning to
acpi-support)
I couldn't get hal+pm-utils to work. Apparently, pm-utils doesn't
shutdown alsa, so I can't remove the module. Even after shutting down
alsa, killing mixer_applet2, and removing the modules manually, the
laptop suspends, but doesn't resume (short disk activity, then nothing),
when suspended using pm-suspend.
