The chip on the board i the screenshot looks vaguely like a Silicon Image chip

If they are Silicon Image, yes, they are supported.

Great stuff - can someone confirm whether I still need to do the folloing for
the latest 2.4.22 kernels in order to get good performance?
# hdparm -d1 -X66 /dev/hdX
# echo "max_kb_per_request:15" > /proc/.ide/hdX/settings
Cheers,
Mark.

I have no idea :( I'm off in libata land, which will soon support
Silicon Image SATA as well...

the answer is yes - there hasnt been an update to the driver. Andre
Hedrick says he has fixed it a month or so ago but has not released it
yet.
btw echo "max_kb_per_request:15" > /proc/.ide/hdX/settings is not for
good performance (it may halve your performance on some drives) it is a
bug workaround.
Look forward to testing libata on Silicon Image.

In -ac pretty much everything "just works". Just finishing off one or
two last issues

The answer is no - the siimage driver isnt maintained by Andre.

Dippy question - is libata a 2.6 thing or is it going to be backported to 2.4?

Mark,
I certainly have seen libata patches for 2.4 - search the mailinglist archive
for libata annoucements or just do a google.
Cheers,
Chris

It's for 2.4 and 2.6 right now. You can get libata simply by using Alan
Cox's -ac patches for 2.4 or 2.6, or download directly from my FTP
directories:
ftp://ftp.kernel.org/pub/linux/kernel/people/jgarzik/patchkits/
(look in "2.4" and "2.6" sub-directories for *libata*)
