There was an -mm3 patch for 2.5.42.  There's an -mm2 patch for 2.5.43 there
now, too :)

It must be a kernel thing; I've got a g550, which should beat a voodoo 3
hands down.  A test with 2.4.19-jl6 confirms this (with reiserfs, rather

Also, by the by, a 2.5.43-mm2 test is now showing similar disk read
results to the -jl6 kernel:
