ThinkPad 755C, audio?

[Matt <matta@myrealbox.com>]

Hi, I am using Debian 2.2r3 on a ThinkPad 755C.  I've read 
that it is possible to make the sound card work by loading 
the ThinkPad DOS audio driver (tpauddd.sys), running the 
SoundBlaster compatibility program (svaudio.exe), and 
booting Linux via loadlin. I was told a few months ago that 
I also needed the ALSA modules for it to work properly.  
Recently, I downloaded the kernel-source-2.2.19, but the 
stable alsa-source would not compile against it (this is 
evidently a known bug - it won't compile on anything 
>=2.2.18pre21?).  So I downloaded kernel-source-2.2.17, and 
alsa compiled flawlessly.  However, I cannot load the 
soundblaster module (device or resource busy) even though 
soundblaster 'compatibility' is enabled.  The DOS program 
(svaudio.exe) does not allow me to set/read the IO, IRQ, or 
DMA.  And I am uncertain what the values are.   Has anyone 
had luck getting the sound to work on their ThinkPad 755C? 
750 Series?  Thanks, Matt
