I'm not using my Dual-Celeron via netboot but I think your run into
Problems because Linux isn't able to load the IO-APIC and remap the
Interrupts because the Paketdriver of the netboot-loader is using an
interrupt. Maybe you can manualy change the settings. This is discribed
in IO-APIC.txt in the Kernel Documentation. I don' know if it would help
but maybe it will ! I think this will slow down your system if you set
your PCI-Irq. to XT-INT.

This is only an idea but i have never remapped the irq's myself !
