I just returned home.
I will answer as much as possible although my remote environment is poor.

This inernal version is maintained by Maria.
It seems to be a little-bit old than the official tree, but contains the
SMP patch.

I tried this, and it works!
#if 0 //original
if (wrapper_builtin_cmdline[0] != 0) {
strlcpy(bootargs, wrapper_builtin_cmdline, sizeof(bootargs));
} else if (builtin_cmdline[0] != 0) {
strlcpy(bootargs, builtin_cmdline, sizeof(bootargs));
} else {
rc = of_getprop(bof_chosen, "bootargs", &bootargs, sizeof
(bootargs));
}
#else //modified
of_printf("@@@@ wrapper_builtin_cmdline=<%s>\n",
wrapper_builtin_cmdline
);
of_printf("@@@@ builtin_cmdline=<%s>\n", builtin_cmdline);
rc = of_getprop(bof_chosen, "bootargs", &bootargs, sizeof
(bootargs));
#endif
With this, cmdline is correctly passed to dom0 Linux.
The boot message is like this
@@@@ wrapper_builtin_cmdline=<xen >
@@@@ builtin_cmdline=<xen >
bootargs = xen -- root=/dev/hda3 sysrq=1 insmod=sym53c8xx insmod=ipr
