My EEE 1000HD also suffers from that.
I looked at the kernel.org changelogs, and found that this was fixed in git 
commit 508f711090e06477081fd94cb9298b1b14dda9ff. [1]

I apt-get'ted the source for linux-image-2.6.31-2-generic, applied this
patch, compiled the kernel into a package and installed it. Booting with
that kernel gives me back the missing volume controls and gives me
decent volume levels.

So, the final 2.6.31 kernel will have this patch, but the impatient can
either do as I did. :)

Alternatively, if you want to compile a kernel and don't use the
headphone output you can add "model=basic" to the "options
snd-hda-intel" line in /etc/modprobe.d/alsa-base.conf. A reboot should
give you decent volume levels. When the fix arrives in the ubuntu
package you can remove the "model=basic" again to go back to
autoprobing.
