Hey, I applied the patch, built a new 2.6.26 kernel an ran getpir again. Two things changed: /* IRQs devoted exclusively to PCI usage */ and the /* u8 checksum. The new file is attached. I also have already tried the new irq_tables.c file by placing it in src/mainboard/asi/mb_5blgp and running the ./buildtarget script again. unfortunately nothing changed.
Thanks, Hannes
/* This file was generated by getpir.c, do not modify!

- Contains the IRQ Routing Table dumped directly from your
