Have you compiled miibus support into the kernel? As a sidenote though, 
if you haven't custom built a kernel it should work straight out of the 
box. Also if you build ACPI or APM support into your kernel, the IRQ for 
your ACPI or APM functionality may be the same as the IRQ for your 
Realtek card; thus if you disable your ACPI and APM support and your 
Realtek card just starts to work for you, the problem is IRQ based ;).
