I've tried some other settings too like setting DOUBLE_CONSOLE_SWITCH=true, but nothing helps when the splash screen is used.
I set everything back to the defaults and just disabled the splash screen on boot.
It seem all about the splash screen.
It triggers a bad interaction between hte resume code and the video driver.
It was working fine previously, so I presume it must be some fairly minor change in the latest X video driver updates or something related.
