The drivers need to load in a particular order. It may be (as it is with 
my Hauppauge 2250 card) that the modules are being loaded in the wrong 
order.

Try removing them and then reloading in the desired order. Looks like 
you have 2 separate tuner sets, with the cx88 ( or cx2388) module as the 
base. If you can get that repeatable, then stick it into rc.local and 
call it on every boot.

This is a workaround and not a fix, but your mythbox will work and the 
WAF will climb, not plunge.
