Prompted by Dennis's comment, I thought I'd be a bit scientific about this, and (a) retested with the packages already installed on my HP NC6220 (behaves as described in bug -- after first suspend audio can be heard through headphones, but not built in speakers), (b) ensure that I had the latest available Ubuntu base packages installed, reboot, and retest, and then (c) try the PPA.
What I found was that after installing the packages (without adding the PPA) and restarting, the audio worked correctly through the speakers after suspend/resume. To verify this was the fix, I changed the boot timeout (/etc/default/grub) so that I could choose the kernel running and restarted to test with both the previous kernel package and the current kernel package. - 2.6.32-22-generic: behaves as per bug, after first suspend/resume built in speakers are silent but headphones work (restarting or hibernating makes built in speakers work again) - 2.6.32-23-generic: works properly, even after 10 suspend/resume cycles built in speakers work immediately after resume 2.6.32-23-generic appears to have arrived from lucid-updates, although http://packages.ubuntu.com/ is unable to find it. So without trying the PPA it appears that the issue has been fixed in the linux kernel update 2.6.32-23-generic. There are a number of ALSA updates in 2.6.32-23-generic according to the change log (many from stable kernel update: https://bugs.launchpad.net/ubuntu/+bug/583414), including some relating to PCI Quirks, and 0dB offsets, but it's not obvious to me which of these affect the snd_intel8x0 ALSA driver (as opposed to hda, hda_intel). If Dennis also has 2.6.32-23-generic installed and running ("uname -a") then that may be the explanation for his fix as well, rather than the PPA specifically.
