All,

1) I propose that the following routine be added to Andrew Johnson's
IPAC library so that we can use ISA based IPAC carriers without
allowing architecture dependent interrupt vectoring to leak into
our IPAC module drivers.

int ipmIntVecConnect (
	unsigned carrier, 
	unsigned slot, 
	unsigned vector, 
	void (*pIntServiceFunc)(void *pIntServiceParam), 
	void *pIntServiceParam);

This will allow unmodified IPAC module drivers to function properly on multiple 
IPAC carrier boards that are not necessarily hosted on the same IO bus. Of course 
this will also require a new entrypoint in the carrier driver jump table. Note that the ISA 
bus does not support interrupt vectoring so we will implement this functionality in the 
ISA carrier board driver. 

2) I propose that the master source for Andrew Johnson's IPAC driver be moved 
into the CVS repository at APS under a new drivers directory so that it can easily be 
maintained by multiple sites.
