Thanks for the tip. I've compiled the 1.0.24 drivers tarball using
./configure --with-debug=full --with-oss=no and it now loads
correctly. I have a large number of controls in alsamixer, having set
model=test in /etc/modprobe.d/alsa-base.conf.

The control names are now generic, but I have found that LOUT1 is the
headphones and LOUT2 is the speakers. There are also GPIO pins 0-3
available. I have tried toggling these, but it does not affect the
jack sense, which still does not operate.

The new alsa-info is at the following URL:

How should I proceed? I've looked at the pci/drivers/hda_intel.c, and
I notice that several "quirk" modes are enabled for particular models.
Is it sensible to try enumerating these on my laptop, or are tables
like this:

   SND_PCI_QUIRK(0x1025, 0x009f, "Acer Aspire 5110", POS_FIX_LPIB),
   SND_PCI_QUIRK(0x1025, 0x026f, "Acer Aspire 5538", POS_FIX_LPIB),
   SND_PCI_QUIRK(0x1028, 0x01cc, "Dell D820", POS_FIX_LPIB),
   SND_PCI_QUIRK(0x1028, 0x01de, "Dell Precision 390", POS_FIX_LPIB),
   SND_PCI_QUIRK(0x1028, 0x01f6, "Dell Latitude 131L", POS_FIX_LPIB),

changing different addresses for each laptop model?

Thanks again for your help so far.
