IRQ assignment on my IBM X24

this seems really poor bios design:
@mini rminnich]# lspci -v -v | grep Interrupt
Interrupt: pin A routed to IRQ 11
Interrupt: pin B routed to IRQ 11
Interrupt: pin C routed to IRQ 11
Interrupt: pin A routed to IRQ 11
Interrupt: pin B routed to IRQ 11
Interrupt: pin B routed to IRQ 11
Interrupt: pin B routed to IRQ 11
Interrupt: pin A routed to IRQ 11
Interrupt: pin A routed to IRQ 11
Interrupt: pin B routed to IRQ 11
Interrupt: pin A routed to IRQ 11
Interrupt: pin A routed to IRQ 11
Pretty much everyone goes to IRQ 11.
And a bunch of Interrupts go unused:
CPU0
0: 3381694 XT-PIC timer
1: 13873 XT-PIC keyboard
2: 0 XT-PIC cascade
8: 1 XT-PIC rtc
11: 77842 XT-PIC usb-uhci, usb-uhci, usb-uhci, eth0,
wlan0, Ricoh Co Ltd RL5c476 II, Ricoh Co Ltd RL5c476 II (#2)
12: 360259 XT-PIC PS/2 Mouse
14: 85559 XT-PIC ide0
NMI: 0
ERR: 0
Is there any reason a BIOS would do this?
