Mike, you rock. Thank you.
In my myth startup script, I placed a "sleep 2" in
between all the modprobes. Now, Xorg no longer pegs
to 100% while on.
Fantastic!
The modprob'ing portion of the startup script now
looks like this:
/sbin/modprobe tuner type=39
sleep 2
/sbin/modprobe ivtv
sleep 2
/sbin/modprobe ivtv-fb
sleep 2
/sbin/modprobe lirc_i2c
sleep 2
/sbin/modprobe lirc-dev
sleep 2
[...other stuff...]
And top shows (while myth is running):
