It can't know about my bridges because all of them are on cards and
they wouldn't won't fit with just 7 entries.

It's not that simple.
The chips behind the bridges are layed out to all use INTA on the
primary bus, but INTA is correctly routed for non-bridged cards.
I have no clue about $PIR and therefor have no idea where irq4 comes
from - any pointer to $PIR documents are welcome.

ISA device are probed later - how would you know that IRQ4 is used
by ISA?

Warner already asked for boot -v output.
I hope things become clear then.
It's just that the system is the NFS server with /home on it.
Therefor I have to wait for a good moment to reboot the box.
Attached is the non -v output with int routing disabled.
