I just bought a Asus M2N motherboard with the MCP61 controllers. With both 
Freebsd 6.2 and Freebsd 7.0-Current-200704 the SATA controllers do not get 

When I patch the src with the below mentioned path they do get found.

However when running the dd if=/dev/zero of=/sata2/test I do not get more than 
35387643 bytes/sec. This figure is the same as before the patch.

I also have problems trying to get the networkcard running. Did anyone have 
luck with this? This would make it easier to get messages/debug and 
pciconf -lv across.
