Hmm, on further thought, it might be objecting to the IRQ enable bits I'm using... they're "sort of" standard, but defined in a later document than the original standard. Perhaps some CAMs don't like them.

The attached patch will disable them just during the link_init procedure.

I've tested both patches now, but unfortunately neither seems to work. :-(

I did notice that CPU utilization jumps to 100 % after loading the modules. This is what top tells me:
