[LinuxBIOS] [PATCH] Update PCI IRQ routing table for qemu target

[Ed Swierk]

I've updated the qemu tutorial at
http://linuxbios.org/index.php/QEMU_Build_Tutorial .

I skipped over the steps I use to generate an initramfs with busybox
and kexec, instead pointing readers to kboot and OLPC buildrom. I can
write up my process if people think it wouldn't be redundant.
