Message:

uspace interrupt controller drivers for i8259 and APIC (non-functional yet)
convert NE2000 driver to use these drivers (not enabling the IRQ in kernel), this solves the "spurious interrupt" issue
(however, on SMP machines this renders the driver unusable for now since the APIC driver does not do anything yet)
