It's a good news. 3 is a workaround for VIA chip, but this seems
applicable to AMD, then.
The only concern is whether the AMD chip really provides the right FIFO
size by the register read for VIA. Could you check which value is shown
by the patch below? If it's 32 or some reasonable number, it's fine.
