I was actually thinking the same thing. I am about to do this actually. I
moved the card into an amd64 dual core system but I need the ir blaster
working in that machine otherwise it's useless.

I am going to have to move it back the single cpu machine and ensure the
cx18 has it's own irq.


Thanks for thinking about this, I really appreciate it.
