Possibly you've misunderstood the code slightly -- for the case of a dual-channel EISA board, the two hosts will have the same interrupt number. So we do need to keep the current code which sets IRQF_SHARED on EISA interrupts. I'm not quite sure why that's not the case for the ABP852 dual-channel VLB card -- possibly each channel has its own interrupt. I don't know if VLB can do that or not.
EISA can do shared interrupts and VLB cannot, according to some quick Googling.
Are you certain you're not confusing adapters with channels? I don't see where the same I/O port is registered multiple times. Or does EISA present multiple channels via multiple I/O ports (multiple advansys_board_found calls)?
