There should be only one interrupt generated for insertion, yes?

Also, when the module is out the PSR has DEBI_E set, but when it's inserted 
DEBI_S also gets set. The SSR has no debi related bits set.

There must be some power line that does not go up, because no read from all of 
the debi address space returns anything other than all highs, except if I set 
the TIEN bit of the DEBI_CONFIG word to high (disable). It will then return 
some value (usually 0xfc) on the first read, then 0 on the rest.

I'll fiddle some more with it later today.
