freebsd stable - Jul 2003 - ALi M5451 Sound Card.

I have post a message about this topic @questions but I have
not get feed back.
My laptop has an ALi M5451 Sound Card. I am using FreeBSD4.8-STABLE
with the "device pcm" activated in the kernel.
At boot time I get this output from the kernel:

pcm0: <Acer Labs M5451> at device 4.0 on pci0
pcm0: unable to map register space
device_probe_and_attach: pcm0 attach returned 6

Searching the Net I have found a URL where there is a FreeBSD 
driver for this card. I have tried without success to contact
by email with the author. 

My questions are: 

- Is this sound card supported on FreeBSD?
- If yes, which driver do I have to use?

P.S: URL info about the freebsd driver:

David,

I wrote a driver for this chip back in 2001.  The motherboard which had
the chip crapped out on me, so I never got around to finishing it (SPDIF
support and such).  The driver is for 4.5-STABLE.  I will send it to you,
but you may have to do some hacking to get it to work with 4.8 -- I
haven't looked at the pcm code in a long time and I no longer have any
hardware to test against, so unfortunately I can't give any support for
the driver, just my old code.

If anyone else wants the code or docs for this chip, let me know.

- Brian

You could try to add this line to your kernel:

options         PCI_ENABLE_IO_MODES

It might help, or maybe not, but it's worth a try.
