I read another place that taking out the battery would help.
And it does!
Today I suspended my 20 GB HP 8540w to RAM. 2.7 GB of this RAM was in use. After resume everything is working as if the 1.6 GHz 4 core CPU has been replaced with a 16 MHz 4 core CPU: I can start multiple processes but they often take up 100% of a core.
Then I suspended to RAM again, removed the battery (this obviously only works if you are on AC), and resumed. Now the machine is working as the expected 1.6 GHz 4 core again.
Plugging the battery back in after resume did not crash anything.
Proposed workaround:
