Yes, exactly that one.

I went to this verion of the kernel originally because on this list I
was told (by Frederik Dannemare <frederik@dannemare.dk>) that the ac
kernel-branch provides UDMA support for the SIS5133 onboard IDE
controller. With a standard 2.4.18 kernel (not supporting SIS5133) you
get roughly 3 MB/sec for disk reads. With 2.4.20-ac2 and UDMA enabled,
I get:

% hdparm -Tt /dev/hda

/dev/hda:
 Timing buffer-cache reads:   128 MB in  0.26 seconds =492.31 MB/sec
 Timing buffered disk reads:  64 MB in  1.42 seconds = 45.07 MB/sec
