No. The IRQ fixup is triggered by subsequent ports not having an
EEPROM.
It will take a minor source code change to trigger the fix-up with your
board.
This was supposed to be handled in a generic way by having special "PCI
fixups" implemented in the 2.4 kernel. That doesn't seem to have
happened, or it doesn't work in this case...

Note that a 21140 with a SYM transceiver cannot do autonegotiation.
This is expected from a 1996-era board
I'll repeat that:

You can purchase Scyld support through "the new HP", as well as
preconfigured clusters with the Scyld system installed.
