If you want my driver set, I can package it up and upload it somewhere. Though it's a bit of a mess that both network drivers and the Intel AC'97 Audio driver need to be installed from Windows Update now, because they removed it from the disk.
By the way, I put a 2.1GHz processor (thanks to some japanese buddy with the CPU stepping tables), 2GB RAM and a cheap SSD in that thing, it's super fast now.

To fix your SD card reader, go to a vista machine and grab C:\Windows\System32\drivers\
sdbus.sys and copy that to the Win7 install into C:\Windows\System32\drivers\
The drivers are at ~347.59MB I'll add the link when I'm done uploading.
