I'm running Archlinux on a Z1390S.

I took Adam's 2.6.37 kernel patch and kernel config, and built myself two
versions of the 2.6.37 kernel:
    1. stock 2.6.37-rc1 from kernel.org
    2. the "Ubuntu" kernel obtained by 'git clone git://kernel.ubuntu.com/ubuntu/ubuntu-lucid.git'

In both cases I was able to apply the patch and get a working kernel that is
ableto resume from sleep, using Intel card.  However, my sound also does not
work.  I'm not using pulseaudio, just basic ALSA stuff; udev loads
snd_hda_intel, etc.  Audio works fine for me with Archlinux's 2.6.35 kernel,
as well as when I was using Adam's 2.6.36 kernel on an Ubuntu install.

Sooo, for what it's worth, here's another vote of "sound does not work on
2.6.37".  I'll try using 'make menuconfig' to pore through the options and
see if I notice anything that could be affecting it.

(still quite new at this!)
