DL360 G5: interrupt sharing between Smart Array E200i and PCI E slot 1

I would like to eliminate interrupt sharing between the E200i Drive Controller and PCI E slot 1.

The box is running CentOS 4.3.

With USB enabled my (abreviated) /proc/interrupts contains looks like:

169: cciss0, uhci_hcd, wanpipe1
177: wanpipe2

With USB disabled /proc/interrupts looks like:

169: cciss0, wanpipe1
177: wanpipe2

Obviously interrupt 169 is in question. I upgraded the Firmware to 8/21/07 to eliminate possible old firmware bugs.

In the BIOS I can swap around interrupts, however, the e200i and pcie slot 1 always match. Do I have any options here?
