I have no idea. I'm not even sure that such docs do exist.
One could expect to find IRQ routing in the tech reference
manual, but there is no such info...

Basically, we need to fill following table:

                Primary bus
        IdSel   INTA    INTB    INTC    INTD
21052   0x0d      -       -       -       -
SIO     0x0e     23       -       -       -
21143   0x0f     44       -       -       -
64-Slot 0x11     43       ?       ?       ?

                Secondary bus
        IdSel   INTA    INTB    INTC    INTD
Slot 0  0x08      ?       ?       ?       ?
Slot 1  0x09      ?       ?       ?       ?
Slot 2  0x0a     27      26       ?       ?
Slot 3  0x0b      ?       ?       ?       ?
Slot 4  0x0c     35       ?       ?       ?
53c875  0x0d     20       -       -       -

These IRQ values were found in the logs and lspci outputs that I got
from Michal 2 months ago. The interesting one is INTB for slot 2 -
it was IRQ assigned to ethernet on a scsi+ethernet combo card. It
allows me to guess that IRQs for slot 2 are 27, 26, 25, 24, for
slot 4 - 35, 34, 33, 32 etc.
We need to find INTA assignments for slots 0, 1 and 3 though.
It could be easily done with any working PCI card placed in
these slots and 'lspci -vv'.
