Hi,

Thanks to the info Brian provided, I was able to set up the 4 ports of the 
sil3114.
Attached is the patch for sata_sil.c, tested on a 2.6.1-rc1-mm1 and tested by 
Brian too.

I used 
if (ent->driver_data == sil_3114)   { ... }

to ensure the 4 ports are probed only for sil3114 , I am not sure this is the 
correct way to do it (so that sil3112 support is not broken). I guess Jeff 
will review that :)

Cheers,
Mik
