OK, I read the INSTALL file notes more carefully - this seems to be a
known problem with this card, but the solution is rather cryptic:

    Note: on some notebooks the buffer address cannot be detected
    automatically, or causes hang-up during initialization.
    In such a case, specify the buffer top address explicity via
    snd_buffer_top option.
    For example,
      Sony F250: snd_buffer_top=0x25a800
      Sony F270: snd_buffer_top=0x272800
    The driver supports only ac97 codec.  It's possible to force
    to initialize/use ac97 although it's not detected.  In such a
    case, use snd_force_ac97=1 option.


So I've added snd_force_ac97=1 to my modules.conf... but how am I
supposed to know the address to use for snd_buffer_top?
Where does one find that information??
I looked in the source for card-nm256.c hoping for some useful
comments, but there's nothing...

I guessed it might be as reported by /proc/iomem but there's a number
of address ranges there and I have no idea which corresponds to
"snd_buffer_top":

f8000000-f9ffffff : PCI Bus #01
  f8c00000-f8ffffff : Neomagic Corporation [MagicMedia 256AV Audio]
  f9000000-f9ffffff : Neomagic Corporation [MagicMedia 256AV]
fd000000-feffffff : PCI Bus #01
  fda00000-fdafffff : Neomagic Corporation [MagicMedia 256AV Audio]
  fdb00000-fdbfffff : Neomagic Corporation [MagicMedia 256AV]
  fdc00000-fdffffff : Neomagic Corporation [MagicMedia 256AV]
