Intel ICH6R sound - pcm0: unable to map IO port space

[Kim Culhan]

Greetings-

The recent Intel ICH6R chipset has 'Intel HD audio' which can
play more simultaneous channels than the AC97 spec systems,
among other features.

This scheme is used on all the newest Intel chipsets supporting
the 775 series P-4 processors.

Apparently this requires more IO resources as the error below
is returned:

pcm0: <Intel ICH6 (82801FB/FR/FW/FRW)> mem
0xfebf8000-0xfebfbfff irq 16 at device 27.0 on pci0
pcm0: unable to map IO port space

To get the driver to recognize the chip, the device ID was
modified:

< #define ICH6ID                0x266e8086      /* ICH6 needs to be
treated as ICH4 */
---
> #define ICH6ID                0x26688086      /* ICH6 needs to be
treated as ICH4 */
642c642
<

Any help getting this working is very greatly appreciated.
