I haven't change the custom kernel for first system in ages. It worked 
flawlessly last November. The hardware hasn't changed either.

Yes, it shows this on the spare system:

OK lsdev
cd devices:
disk devices:
    disk0:   BIOS drive C:
        disk0s1a: FFS
        disk0s1b: swap
        disk0s1d: FFS
        disk0s1e: FFS
        disk0s1f: FFS
        disk0s1g: FFS
pxe devices:
OK

I doubt the loader is at fault. It could be how the IDE controller is 
handled by the faulty kernel.
