I've had this problem before trying to install xp onto the m1330, but i just bought a new hdd to try it again.
i'm using all the drivers that dell used to provide for the m1330 in xp 32bit. What happened to those drivers? I saved copies of them, but dell removed them? wtf?
I've tried these Bluetooth drivers:

as well as:
http://drivers.anycom.com/bluetooth/...5-1-0-4200.exe

and these drivers for the Sigmatel audio:

(the one dell listed as the xp audio driver for the m1330)
and also this one:

although this one doesn't work at all. :-(

the problem i have, with all the combinations of these drivers is that after i install the audio, everything works fine. then i install the bluetooth stack, and after a restart or 2, the bluetooth audio driver disables the sigmatel audio driver, and i get the yellow ! in windows device manager.

i'm not the only one who's had this problem:
