Just as a follow up, after reverting the above and booting successfully,
this is what /proc/interrupts now shows:

claymoor:~# cat /proc/interrupts
CPU0 CPU1 CPU2 CPU3
16: 31 24 35 19 MPIC Level pata_amd, serial
17: 374 421 434 381 MPIC Level ipr
20: 0 0 0 0 MPIC Level ohci_hcd:usb1, ohci_hcd:usb2
21: 135 140 152 146 MPIC-U3MSI Edge eth1

BAD: 621

So MSI seems to be being used successfully on the ethernet controller,
pointing to an ipr specific problem.
