I just wanted to let you know that I submitted a patch (PR identifier is 
port-i386/30795) that adds support in -current for the IDE and SATA 
controllers found in the Intel ICH7 (82801G) chipset. I have been testing 
this patch for a few weeks without any problem.

In case you would like to test it, the patch is attached below (it has to be 
applied to src/sys/dev/pci/piixide.c).

Marcello
