Nick and Jarod:

Thanks for your time.  Still working to get the serial blaster working.
1) I corrected all the typos, but I could not find the last one you indicated, above.
2) I had earlier yum installed gnome-lirc-properties from the regular repository.  Its broken of course. Could this have changed something?
3) permissions on lirc.modules are ok.

still getting:

[root at MYTHTVNEW ~]# lsmod | grep lirc
lirc_mceusb            16308  0 
lirc_dev               12221  1 lirc_mceusb

4) For Jarod, after running 'modprobe lirc_serial debug=1
dmseg

Thanks guys.  Make I should give up, unistall the Fedora lirc with yum and compile from the source code?
