Thanks to everyone for all the suggestions... I tried a bunch of them - too tired to enumerate them now; stuff like using AppleJack, etc., and then decided to put the B&W's original 300 mHz CPU back in, and reset the jumpers accordingly...
And to my great relief, it's now running Tiger 10.4.11 flawlessly, albeit slower than it ran with the 450 CPU... No hanging at all, not even when running two browsers and lots of open windows. Even when 'activity monitor' showed the two browsers were hogging 80 - 96% of RAM... I guess I naively thought that, since I was using a chip from the same (but speed-bumped) model, and it fit so nicely, that it wouldn't be the headache that it turned out to be. (BTW, if anyone out there does know how to do that safely, I'd still like to know.) The only issue left - and I suspect it's not really an issue - is I STILL don't get the startup chime-sound, though all other sound are fine.
