I have a Winchip 240MHz CPU, and added it to /sys/src/9/pc/devarch.c's X86type
structure as below:

/*
 * WinChip 240MHz
 */
static X86type x86winchip[] =
{
	{5,	4,	23,	"Winchip 240MHz",},		/* guesswork */
	{ -1,	-1,	23,	"unknown", },		/* total default */
};

I also added lines in cpuidentify() function in the same file as:

	if(strncmp(m->cpuidid, "AuthenticAMD", 12) == 0)
		t = x86amd;
	else if(strncmp(m->cpuidid, "CentaurHauls", 12) == 0)
		t = x86winchip;
	else
		t = x86intel;

Is that all the neccessary patch to use this CPU?  Do I forget anything?
The chip is now recongnized as 240MHz "Winchip 240MHz".
Woever, when I run it longer time, I get hangup of the machine. :-)
I'm wondering this is just the heat problem or something else...
