Toshiba Satellite sound problems

Hello,

I jumped to Redhat 9.0 from Mandrake 8.2 ... the redhat autodetection thinks 
my sound is ALi Corporation|M5451 PCI AC-Link Controller Audio Device, which 
tries to use trident.o via modprobe and fails "no such device" ..

The hardware is a Toshiba Satellite laptop, model 1800-PS183C-00VF1P .. I 
don't know what sound hardware is bundled with this.  I tried calling 
toshiba technical support, and for some reason they didn't want to tell me 
what my sound hardware is.  They suggested I search the internet using my 
model information, but I already tried that before calling them..

I'm keeping myself hopeful by reminding myself that since Mandrake 8.2 
supported my sound hardware, it must be doable (rather than there being no 
hardware support developed for linux yet).

Also, I tried using sndconfig and clicking through absolutely all the sound 
drivers it makes available to me... no go :(

I would be grateful for any help here, as my RH9 experience has been 
otherwise a happy one
