Looks like a 256AV without AC97 Codec.
Boot the machine without pcm enabled, then issue as root pciconf -l, you
should see an output like this one :

On my laptop, the neomagic is the 0x00dd1014 card. Check the card number
corresponding in your laptop and then add it to the badcards struct in
neomagic.c
/usr/src/sys/dev/sound/pci/neomagic.c
...
static void nm_wrbuf(struct sc_info *, int, u_int32_t, int);
static u_int32_t badcards[] = {
0x0007103c,
0x008f1028,
0x00dd1014, /* add after this one */
};
#define NUM_BADCARDS (sizeof(badcards) / sizeof(u_int32_t))
...
Recompile your kernel with pcm enabled, the machine shouldn't hang
anymore.
device pcm doesn't work on my box, I have to use the following :
device pcm0 at isa? port 0x530 irq 5 drq 0 flags 0x11
following the settings found in bios and man pcm.
