I used it on my son's Toshiba L455 and I didn't get sound or netwerking, but it does what I wanted it to.

I used the SATA and the SD drivers, removed the FireWire. Try it with the minimum, then add to it. Try going to Acer's website and search the forums, there is a section about OS X on the D250 and use the recommended settings as a start

I added NTFS read/write capabilities, and moved the User's home to the Windows 7 partition, overlapping its desktop.

What little he does stores on the desktop, and when he reboots, its on his Windows desktop and he is happy.
