One possibility is that:
    CGContextRef cgContext = CGBitmapContextCreate(imageBuffer, size.width(),
size.height(), 8, bytesPerRow,
        colorSpace, grayScale ? kCGImageAlphaNone :

in ImageBuffer::create() could be crashing (or smashing memory) instead of
failing gracefully like it does on Intel.  I'm not even sure we're hitting that
line (depends on how much memory you have available), but someone trying to
debug this on PPC should see if guarding that call against really large values
fixes the problem.  (In which case this would definitely be a CG bug, code
guards should be added to WebKit and this bug moved into Radar.)
