I'm actually surprised that this could ever work at all, since -soundhw 
is a legacy PC option and certainly isn't included in regular testing of 
the PPC Mac machines.

The confusion comes from the fact that the mac99 machine has multiple 
PCI buses, and my guess is that recent fixes the 3.0 dev cycle could 
have broken an assumption in the old option code.

In theory you should be able to get the correct configuration with 
something like this:

./qemu-system-ppc -monitor stdio -device ES1370 -M mac99

But I'm afraid this configuration is effectively unsupported.

Is this a regression? Certainly it's not an image that is part of my 
regular test suite. And what is your host platform? Does a 64-bit build 
make any difference? What about using GTK and/or VNC instead of SDL? 
Does disabling the sound hardware change the responsiveness?
