The plan9.ini essid=string should be forcing it.  It does exactly what
the echo does  I take it you've made sure that the case in the essid
option is set in the particular case of the plan9.ini that you're
falling through?

What kind of card do you have?  You might try sticking a print into
/sys/src/9/pc/etherwavelan.c to see if it is getting set in the initialization.
In wavelanpcireset() and wavelanpcmciareset(), you'll find the following
bit of code:

	for(i = 0; i < ether->nopt; i++){
		if(p = strchr(ether->opt[i], '='))
			*p = ' ';
		w_option(ctlr, ether->opt[i], strlen(ether->opt[i]));
	}

Stick a print there to see if its calling w_option with an essid
set.  You might also stick a similar print in w_option.
