Thing is, I want HDMI and analog video simultaneously. If I can have PAL but no digital video out then the whole exercise is moot. Incidentally, the SODIMM has 200 pins. Pin #166 is TVDAC. I haven't tried my RPI with both analog and HDMI connected, maybe should try that first. The compute module shouldn't differ too much from it. The hdmi_force directive seems eerily familiar.
