[linux-audio-user] Setting IRQ on intel8x0-card

Hi list.

I have a question regarding IRQ-assignment for an on-board card identified as an Intel 82801DB-ICH4.

It is a crappy card, I know, and you probably ask yourselves why on earth I would want to put any effort
in configuring such sub-standard equipment. The question, fortunately, is a bit broader than that. I'm writing some swedish docs
on how to set up a Linux-system as a DAW, and see the need to do it thoroughly. :)

As of now the card shares IRQ with the eth0-card, which isn't super if one is to set RT-prio 99 on it.

Is there a simple way in setting a specific IRQ without the need for a super-BIOS that does it for you? Since I have
a laptop the option of shuffling the PCI-cards isn't really viable. :)

I think I remember from my early days of kernel-hacking that it is possible to set IRQ with modprobe options, but it
was a while ago. I searched through the kernel tree in the /sound/pci/intel_8x0.c file to no avail.

Any feedback is welcome, with the sole exception of "Why?" ;)

Regards,
Mathias
