If you remove the soundcard from devce manager, next time you reboot and it asks for a driver, simply say "Have Disk." Then you can use the win98 driver by just telling the machine where it is.

If the machine is installing the drivers automatically and not letting you select a driver, you will need to find the INF file for the Win95 version of these drivers. Once you have the name of that INF file, find it in c:\windows\inf directory and delete it (or move it out of the INF directory if ou want to keep a copy). Then, again, delete the SC from device manager and reboot. It will now ask you for a driver for the new device it detected.
