Since we were speaking of sound on that Thinkpad, I might as well ask my question.  Anybody have 
the Yamaha opl3sa2 sound chip, using either the module opl3sa2 or w/ support compiled in the 
kernel?  I am going to compile the 2.4.23 kernel w/ support for my sound chip, but I don't know the 
exact line to pass to the kernel in lilo.conf.  I have tried without success to load the module on 
a 2.4.21 and earlier kernel, but couldn't get something right on the options to pass to initialize 
it.  Mine appears to be a ISA non-PnP type.  Odd in a laptop, I know, but lspci and the isapnp 
tools don't see the chip.   If you could post your parameters exactly as you put them in lilo, 
grub, modprobe, etc it would be helpful.  I can then alter for my settings.
