[PATCH] i91uscsi.c misreads BIOS settings

Here's a patch for i91uscsi.c as delivered with the 2.4.0 kernel to correct the problem of it reading the BIOS settings for double the SCSI id that it should be looking at. This is a two liner to correct this problem but I've done some fairly major cosmetic surgery on the rest of the driver -

A quick perusal of the 2.2.18 source code (I don't have a copy of 2.4.x handy) shows that it's directly related to the number of IPIs (inter-processor interrupts) the system has taken. I'm not real sure under what conditions this occurs, but it's someplace to start... tw
