Even manually insmod'ing them does not work: you'll really need to resolve 
those interdependencies that cause the dependency loops first!

Using a kernel with both Teles and ITK support unselected, depmod -a no 
longer complains.

First I left the old modprobe config:
options        hisax type=9,11 protocol=2,2 irq=10 io=0x398

When I modprobe hisaxdiva with that, I get:
# modprobe hisaxdiva

I then changed the modprobe config to just:
options         hisaxdiva protocol=2

When I 'modprobe hisaxdiva' with that, the result is a lot better:

Issues I can see in this dmesg output:
- the module licence warning for libhisax
- I've never seen the last two lines before

Otherwise the driver seems to have loaded correctly and lsmod now shows:
