As it can be seen below, a native SATA150 drive is connected
to a SATA port implemented using that Marvell chip hooked up
to the ICH4's parallel ATA133 port and this way the drive is
only recognized (and used) as UDMA33:

hdc: 312581808 sectors (160042 MB) w/8192KiB Cache, CHS=19457/255/63, UDMA(33)

As far as I can remember someone (Jeff Garzik?) suspected the
SATA cable not being recognized as a 80-conductor thus >=UDMA66
capable cable. Then it was told that there is a fix underway that
will be included in the 2.4.23 kernel. The above snippet shows
that the 2.4.25 kernel still has this problem. Any comments?

You want to use a 2.6 kernel and talk to Bart, and Jeff about this...

Well, I don't really want a 2.6 kernel on that machine (yet) because
in my opinion it is not stable enough for a production system.

What problems are you having?

Would it be hard to fix that in 2.4?
