It's a sanity check, which I removed (because it's worse to panic in a
2.4.x kernel than it is to have the sanity problem). But the sanity
check does show that there is some problem in ahc_pci_map_registers():
it calls "ioremap()" with interrupts disabled, which is rather broken.

I don't know that driver well enough to understand why the heck it would
keep interrupts disabled over apparently a _long_ stretch of time during
probing. The irq disable code seems to be somewhere else..
