Last night I got the thing running with both the Trident Cyberblade drivers and the Yamaha YMF715 drivers. Win95 OSR2, total install size about 90M. Fits nice in a 127M partition.
The Cyberblade drivers: Unzip in a spare directory and do *NOT* run the setup program (it'll give you screwball drivers that will leave "mouse tracks" as you drag your windows around). Right-click on the .inf file and select "install" instead.
The sound drivers: Unzip, go into "DISK1", run setup. Reboot, go to ControlPanel -> System -> DeviceManager -> OPL3-SA Sound Board -> Properties, and update the driver even if it says you don't have to. Tell it you "Have Disk", and Browse in \WINDOWS\Temp\Sax. You'll find something that'll give you sound.
Weirdest install procedure I'd ever seen; in neither case did the normal standby of "run SETUP.EXE" work.
