Uh, no. That is the default, not the only option. Even the u-blox 5
supports:
4800, 9600, 19,200, 38400, 57,600 and 115,200.
Use the UBX-CFG-PRT command to change the speed.

Also heck the optiopns pased to the kernel at boot time. They will be
at the top of the dmesg ouput after a boot.
On some distros you also need to edit the /etc/inittab file which
tries to attach getty to thaty port.
