This is true.

Not to mention, that ksoftirqd spins in an infinite
loop if the cable isn't connected (regardless of ksoftirqd's priority).

This is not true. The infinite loop is only hit when ksoftirqd is a real time task. I 
think you got confused by the different patches we tried. That dirty hack of yours 
with the workqueue was the one hanging with the cable disconnected. ;o)
