Sound Card ALi M5451

[David Rio]

Hi all:

I am trying to configure my laptop (hp omnibook xt6200) with FBSD and 
I'm a bit stucked with the sound card: it is a ALi M5451. It seems 
that it is not supported (I am running 4.8-STABLE).
I have found a patch on internet to get working this card (check: 
http://home.att.ne.jp/delta/athlete/m5451_e.html) but I want to 
know your experiences with this card before to try the patch. 
Anyone has any experience with this SOund card and FreeBSD? 

Thanks.
