It reboots in about 15 seconds by itself. The instructions say looks for IRQ sharing. So on Linux, I see IRQ 11 for both a WinModem and my video card. I also see 2 USB's and an ACPI all on IRQ 9. Is this a problem? Might be, GNU Mach doesn't like it when IRQ's are shared. Try removing a device or recompiling GNU Mach with less drivers.
