PowerTowerPro, most comparable to the 9500 AFAIK. I also have a
500/1Mb PowerLogix upgrade card in it.

Yes, I've known this for a while. But this leads to a long-standing
question of mine: how is it that the Twin Turbo card is still somehow
recognized? Because the imsttfb driver will load and appears
functional in console mode (although not in X as described on other
linuxppc lists).

Thanks I will try this.

Given my list of cards, are there any other general pointers as to
which bus which cards should go? The order I have now took a long
time to create - I'm not sure if it's the unique workable one, but
several other orders cause OpenTransport crashes when I am running
the ixTV (!). But it looks like removing cards and/or changing order
is my only choice, given 2.2.18's new proclivity (for me anyway) to
not boot - bummer. I'll be back with a report when I can try it all.
