popsman.prx starts the Media Engine and sets up audio through them. The
ME reset, bus clock and AVC reset are the calls the older NIDs already
have. The others set bits of registers lowio.prx 6.61 writes for them
(0x50 bit 15+n, 0x58 bit 16+n, 0x60 bit 18, 0x78 bits 7+n and 11), and
C36775AD (called with 0, 1 before audio is set up) isn't read yet. The
system register device now keeps every register it doesn't model.
Under --vsh these stand in for lowio.prx's own, which write the same
registers.
