> On a Quadra 800 machine Linux sets via_alt_mapping to 1 and clears port B bit 6 to
> ensure that the VIA1 IRQ is delivered at level 6 rather than level 1. Even though
> QEMU doesn't yet emulate this behaviour, Linux still installs the VIA1 level 1 IRQ
> handler regardless of the value of via_alt_mapping which is why the kernel has been
> able to boot until now.
