If you could turn off the driver that should certainly work.However, the 
usual way to handle this kind of problem is to set up a udev rule which 
creates a device with a fixed name which works the same way as lirc0.

No box at hand right now, but perhaps a rule like:

KERNEL == lirc*, DRIVER == mceusb, SYMLINK += lirc-mceusb

should be able to create a fixed device called /dev/lirc-mceusb which 
could be used instead of /dev/lirc0, but always points to the mceusb 
card. This is untested, and you might need to use "udevadm info" to find 
the attributes, see  e. g., [1]. Google will show you lot's of udev 
rules for linking devices.

Please report back, this is something which is missing in the upstream 
lirc documentation.

Cheers!
