I have the same problem with the kernel 2.6.24 and a Dell Vostro 1510. Internal Mic doesn't work. I have downloaded the official kernel source 2.6.26. I have configured and I have compiled the kernel. I attach my .config file. Then the internal mic works great!. The only detail is that in alsa mixer you must select as recording device the digital input.
Selecting digital input as recording device is not a bug, according realtek 268 HDA controller schematics the digital input is the internal mic in Dell Vostro 1510.
I tested the kernel that come with intrepid (Ubuntu 8.10) but it doesn't work.
