Thanks Lenard, I didn't know about
www.google.com/linux.
So, after many reboots and reading
mailing list it seems it's problem of some kind of Intel motherboard and their PCI bus. To be honest - I didn't understand it
In mailing list recommends to make some changes in kernel source and it was probably released some patch or something.
In ArchLinux forum I saw
another way. In some
czech mailing list was recommended to boot with parameters "pci=usepirqmask,biosirq irqpoll acpi=force".
I just booted with parameter "pci=noacpi" and it works. I mean Yenta has its IRQ #11 and is happy. Unfortunately my PCMCIA cards still doesn't work, but this will be another story from dark dusty mysterious corners of linux kernel

At least I hope so
