Well I found partial answers on some of the laptop forums. Sound is now
working for me. Here is the recipe with the secret ingredients :-)

1. Obtained nLite and read in my XP install CD
2. Downloaded Intel chipset drivers, insert them into "new" CD with nLite
3. make disk image backup of vista in case you need it
4. use "new" install CD to install XP onto SATA disk
5. Nvidia driver - found 15655.exe on the internet - this worked
6. Intel for the 4965 wireless driver
7. marvell yukon pci-e gigabit driver from their site
8. Sound was a real pain - there are tricks - there are two sound systems
realtek and sigmatel. Give up on the realtek for now.

a. Get the sz640 XP sigmatel driver from sony
b. disable the realtek device (10EC:0262)
c. don't disable the sigmatel device (8384:7664)
d. if kb835221 (a microsoft update) is installed then de-install it
e. install kb888111 (a microsoft update)
f. install the sz640 XP sigmatel driver
g. you may need to disable \MEDIA\ROOT\000 if it shows up

9. Some misc devices (memory card, modem, pointing, bluetooth, etc) the
drivers supplied with vista may have worked - or XP supported them.

So I am still unable to get the camera to work - I have tried several of
the various Sony drivers for the camera. It looks like the same camera
is in the other Sony laptop models that Sony has released XP downgrades
for.

Others have spent time trying to get the S1/S2 buttons to work and are
reporting success but I didn't care about these.

Later
