To expand this bug report a little, this is a suggestion to backport changes to snd-hda-intel that improve the support of the Realtek ALC262 codec as used in Fujitsu Lifebook E & S series laptops (specifically ICH8-based machines such as the S6410 & E8410).
These should apply with minimal fuzz on top of the 2.6.24 kernels you are using for Hardy Heron. Please apply in the order listed:

Using the ALC262_FUJITSU model automatically with a quirk table entry:

Enabling use of the docking station headphone port:

Enabling use of the 'beeper' aka PC Speaker signal:

Checking the initial jack state, to avoid having both the speaker & headphones on simultaneously:

These have all made it into the upstream 2.6.25 (first 3) and 2.6.26-rc3 (last patch) kernels with no bug reports on the alsa-devel mailing list.
