There is most likely another bug in vortex_fifo_setwtvalid(vortex_t *
vortex, int fifo, int en)

Do anyone know how to multiply 32bits x 32bits in I386/AMD64 ?
We need to obtain the upper and lower 32 bits of the 64-bits product to
calculate the wt parameters.
((sr << 0xf) * 0x57619F1)
in au88x0_synth.c
