I'm a bit confused, now, because I see "ioapic*        at mainbus? apid 
?" line in XEN3_DOM0 which I include to my customized kernel (and I'm 
not deconfiguring it later). Also binary contains it, I believe:

$ zcat netbsd-XEN3PAE_DOM0_MASTER.gz | strings | grep _CFG_.*ioapic
_CFG_###> # boot messages with MPBIOS, acpi and ioapic can be quite large
_CFG_###> ioapic*\011\011at mainbus? apid ?

I also tried to enable PCI_INTR_FIXUP and also enabled "lapic" in Xen 
command line. But it still tries to bind IRQ 255.

Is there some other, way to enable ioapic?

Ok. I tried it the other way around - to disable ioapic with "no ioapic" 
in my kernel config. And the kernel booted, also rtk0 adapter connected 
to cardbus was recognized, but when I did "ifconfig up rtk0" whole thing 
gets frozen. This is excerpt from dmesg:

cbb0: cacheline 0x8 lattimer 0x20
cbb0: bhlc 0x822008
pci_intr_map: no mapping for pin B (line=ff)
cbb0: couldn't map interrupt
cardslot0 at cbb0
cardbus0 at cardslot0: bus 3
pcmcia0 at cardslot0
...

Thanks,
