IIRC, when I did this the S3Triofb code was full of OF'isms, so it's
really only useful on some CHRP machines.  And just checking, it's still
got:
int __init s3triofb_init(void)
{
        struct device_node *dp;

        dp = find_devices("S3Trio");
        if (dp != 0)
            s3triofb_of_init(dp);
        return 0;
}

So it certainly won't link on !CONFIG_ALL_PPC.

But more importantly, that needs to be cleaned up a bit to be more like:
if [ "$CONFIG_PPC32" = "y" ]; then
   if [ "$CONFIG_ALL_PPC" = "y" ]; then
      ... apple drivers ...
      ... S3Trio ...
   fi
   ... other drivers ...
fi
