Well, S3triofb hasn't even compiled for ages. I've attached a patch
that allows it to compile, and removes the dependency on OF. However,
it still requires some sort of firmware to initialise the card. I've
added a little hack so that it ignores the card if it wasn't initialised
by the firmware, since the driver doesn't have the code to initialise it
It works on the 7043-140 using a PReP kernel, and has been tested by
quite a few people. Unfortunately, I no longer have an S3Trio card (and
to be honest, I know very little about graphics cards).
IMHO it's worth applying the patch as a working (just) driver is a
better starting point than a non-compiling one.
If there are other PPC systems that bring up the S3Trio in 640x480x8
mode then I suppose the driver will be applicable to them also....
