I'm a little late on this thread but in regards to the SATA support. 2.4.29 in
my experience is really the first kernel that decent SATA support (i.e. much
better data throughput). I think that would corresponse to 2.6.9 or .10 but
even before you get into all that. I am curious to know what do you mean by
"standard Linus kernel". Do you not compile your own kernels for the hardware
platform being used?
