I've certainly messed up the osc fuse settings a few times.  I have usually 
recovered by sticking dip parts back into my STK200 and reprogramming.   I 
think you'll find the STK300 has its own external oscillator that drives 
the XTAL1 pin, the same as the STK200.

So Tim's method above should work.  If not I'd be looking somewhere 
else.   Any chance of checking the XTAL1 input with a CRO ?   What program 
are you using to drive the STK programmer ?  Can you elaborate more on "not 
waking up ?".

Cheers

Matthew
