Ok, I tried the acpi debug procedure. The driver that was the 'likely culprit' was serio0 in my case. I looked in the lsmod output and found a driver serio_raw, which I added to the MODULES in acpi-support. This seems to have fixed it, I have tried to suspend/resume more than 10 times, and it worked every time. But I'm not convinced it's solved yet, normally I suspend/resume several times per day, so in the next few days I'll let you know. As a reference for other users my /etc/default/acpi- support: (dell latitude D820)
