Or is Linus' suspicion, and X defaults to something like nice -5? (e.g. on Debian type of systems) but ... i havent seen problems with Firefox and flash myself. My 3 years old son's favorite kid's site is fully based on flash, and the 833 MHz laptop is still usable remotely while he browses around on it. It's Fedora Core 4, and X is not reniced. but if the X server is not reniced then it would be nice if i could reproduce the starvation ... which site is the one triggering it? (and could you check www.egyszervolt.hu, and click around on it, does it trigger similar starvation problems too?)
