No, the w1 system is not hardwired to GPIO4, it depends which kernel
drivers you have loaded.
The w1-gpio driver can use any GPIO, which one to use on the raspi is
defined in arch/arm/mach-bcm2708/bcm2708.c, line 81
// use GPIO 4 for the one-wire GPIO pin, if enabled
#define W1_GPIO 4
and can be set by the kernel cmdline option
bcm2708.w1_gpio_pin=8
But independendly of the w1-gpio driver, there are three other host
adaptor drivers, most prominently for your problem the "ds2482" module.
That ds2482 kernel driver interferes with owfs on the chip when loaded
and when owfs is used with the --i2c=ALL:ALL option. Then, both send
control commands to the chip, and the mix of those won't work correctly,
of course.
Kind regards
