ICH7 soundcard (82801G, not 82801GB) support?

[Anders Nordby]

Hi,

I have a 82801G ICH7 sound card:

pcm0 at pci0:27:0: class=0x040300 card=0x10831734 chip=0x27d88086 rev=0x01
hdr=0x00
    vendor   = 'Intel Corporation'
    device   = '82801G (ICH7 Family) High Definition Audio'
    class    = multimedia

The attached patch adds it to the ich driver. It fails to attach,
however:

pcm0: <Intel ICH7 (82801G)> mem 0xf0000000-0xf0003fff irq 18 at device
27.0 on pci0
pcm0: unable to map IO port space
device_attach: pcm0 attach returned 6

Anyone else having this problem, or who solved it?

PS: I'm running RELENG_6 from today. Yes, I tried
hw.pci.allow_unsupportable_io_range="1" in loader.conf. No, it didn't
help.

Cheers,

-- 
Anders.
