[OOPS] Quicknet PhoneJACK usage in 2.4.4 isn't a good thing

[OOPS] Quicknet PhoneJACK usage in 2.4.4 isn't a good thing

Problems:

1) loading the ixj module while X is running causes a kernel OOPS in the 
swapper, killing the machine flat out.
2) after successfully loading the modules and starting X to use gnophone 
GUI application, answering a call will cause a crash.  Sometimes just 
the inbound ringing is sufficient to crash.

The CVS version of these modules doesn't kill the machine but it still 
OOPS and a reboot is necessary to remove the broken modules.

Here is an oops of the module loading.  I'll be posting more oopses as I 
can catch them.

Here's the followup with the CVS (5/3/2001) version of ixj.o and 
phonedev.o.  First inbound call was fine, answered, sent voice data, 
pushed buttons, all is well.  Second inbound call crashed the modules.  
All further attempts to route a call to it have failed.
