With Intel's 875PBZLK board, I've had no trouble at all with 5.1-R
or -CURRENT.  The GigE, PATA, SATA, and USB work for certain,
although the SATA drives are detected as ATA-133.  But Gigabyte
uses different chips for some of these components, and as you
point out, there are problems with these.  The point is that
there's nothing inherently incompatible about the i875 chipset
itself.  Unfortunately, I haven't had a chance to try 4.X on this
box yet, so I can't say whether there are any issues there...
