alt-apple-P-R not working

Can't zap the pram anymore. When booting, the keys alt-apple-P-R are just ignored. I tried to reset SMC by keeping the power button pressed while booting: one long beep and boots normally. Thanks for your hints!

MacBookPro 2.0, Mac OS X (10.5)

Did you enable Firmware Password Protection? That blocks PRAM reset, among other things.

Also, "+keeping the power button pressed while booting+" is not the way to reset the SMC. This is:
