The number following "SUBSYS" is, I believe, unique to each individual 92XX file; run a search on the WDM folder for files containing that number to locate the INI that your computer actually looks at. Comparing this to the changes between the stock and unlocked 92XXM8-8 files provided here, it looks pretty much like the controls are unlocked by adding a few lines to the bottom of the file; copying the lines from the bottom of the M8-8 and pasting them into my M8-3 successfully unlocked the controls, although whether or not they all function is yet to be determined.
Note: This is not necessarily recommended; recklessly modifying drivers can render a system unusable. Reference only, eh?
This worked for me more or less. I am using an XPS M1530 with Windows XP SP3. I haven't tested all the features (mostly because I'm not sure what 80% of them do, lol).
For anyone interested, I already had the unhacked driver installed. From there, I opened up "Start Menu > Settings > Control Panel > System > Hardware (Tab) > Device Manager (Button) > (Expand) Sound, video and game controllers > (Right Click) SigmaTel High Definition Audio CODEC > Properties > Details (Tab)" as told by TheMike and looked up the number after SUBSYS. It happened to be 1028022E. After downloading the appropriate driver, I opened up the "Sthda.ini" inside the Audio Driver's WDM folder. There I found that "HDAUDIO\FUNC_01&VEN_8384&DEV_7616&SUBSYS_1028022E=92XXM8-3.INI". In other words, 1028022E equals 92XXM8-3.INI. After opening up 92XXM8-3.INI, I compared the hacked file with it. There's several extra lines at the end of the hacked file. I just pasted those at the end of 92XXM8-3.INI and saved. Then I went to Add / Remove Programs and uninstalled my current SigmaTel Audio Driver installation and installed the hacked driver.
To reiterate, this hack does, at least, install correctly with XPS M1530 using Windows XP SP3. Thanks for sharing Spatz.
