IRQ routing conflicts / Assigning IRQ 0 to ethernet

Hi

It's been a while since I'm trying to get this running, but so far no
luck...

The laptop is a FIC 360+ ( www.fic.com.tw ) with an on-board ethernet
card. Comparing the pci scanning from other postings, it seems to be the
same as some model of the Gericom family.

I have tried different kernels and upgraded the BIOS, but still no good
results. Currently I'm using kernel 2.4.19-pre4, but have tried many
others.
I have also tried different PCI access types on the kernel ( auto,
Direct and BIOS ) and no luck.

The main problem is that it can't assign an interrupt for the
controller, plus I get irq routing conflicts on other devices...

Here are the logs

Regards,
Luis
