old SiS built-in video card on 12.10

[Thufir Hawat]

I'm running older hardware on 12.10, and, by adding this xorg.conf, am 
able to boot to xfce4:

thufir at dur:~$ cat /etc/X11/xorg.conf

My concern is that the login process is a bit long, and after login the 
monitor gives many "autoadjusting" messages before it settles down.

1.) do I have anything to be concerned about, switching drivers?
2.) is it worth investigating alternatives, like switching back to the SiS 
driver but downgrading X11 with a ppa?
3.) is this worth even reporting as a bug?  I might very be the only one, 
or one of a handful, of users running Ubuntu 12.10 on this built-in SiS 
card.  I imagine Ubuntu and X would point fingers at each other.

I get it that old hardware cannot get infinite support, things progress, 
etc, but if the old SiS driver worked under 12.04 why can't I use the 
same driver?  Seems a bit sketchy.
