Hello,
I found that with a recent version of scanpci, the -v parameter must be
used in order to get PCI boards'IRQ. It then lists the IRQ in
hexadecimal format (pirq=0x0e,0x0a,0x0b,0x0e for example), which I hope
are syntaxically correct for the pirq option of the kernel.

the following script tries to figure out such a default pirq= line from
your PCI configuration:
- echo -n pirq=; echo `scanpci | grep T_L | cut -c56-` | sed 's/ /,/g'
+ echo -n pirq=; echo `scanpci -v | grep T_L | cut -c56-` | sed 's/ /,/g'
note that this script wont work if you have skipped a few slots or if your
board does not do default daisy-chaining. (or the IO-APIC has the PIRQ pins
