Dell :: Bluetooth Driver And My Sigmatel Audio Driver Not Working XP

here's the problems:

1. The damn CPU whining? I know everyone has it. Dell said last time I called that they're working on some way to fix it. The new A09 Bios didn't seem to do anything for me, or anyone else apparently according to dell's support forum. What's up with that?

2. My laptop wobbles on the top right and bottom left corners. it only wobbles if I use my 6cell batt, and it doesn't wobble w/ the 9 Cell. So does that mean the 6cell's rubber feet thing on the top right corner isn't high enough? Can dell fix that?

3. The "increase volume" media button thing isn't as responsive as the other ones. i have to press really hard to get it to respond. all the other ones i just tap it lightly, and it works.

Here's some questions that I know Dell has no clue what to do with:

4. I'm currently using Vista Ultimate on this only because I couldn't get my bluetooth driver and my sigmatel audio driver to work properly on XP. since dell hasn't released a xp bluetooth driver, i used WIDCOMM 5.1 stack, and the bluetooth headset and stereo headset drivers would disable the sigmatel drivers. really annoying. cmd51229 says he's gotten it to work:..........................
