Re: Problem with Vaio touchpad
This sounds like the same thing I sent a mail before but for dell
inspiron 600m... I'm copying an answer I got pretty useful:

I have the same problem with an old vintage Sony Vaio PCG-R505JL, From
my research in the kernel lists, it seems that, for 2.6.11 maintainer
selected to disable the hardware double tapping of Alps touchpad, in
favor of doing it by software in the driver, as the kernel message
says.
Unfotunately it does not work well for most people like us, so in new
kernel version 2.6.12, when released, the driver eill return to use
hardware tapping. Until them you can try use the psmouse proto=imps,
as suggested in the Fedora list (as an option to kernel in grub or
lilo if psmouse is in kernel, or as an option to module, in
modprobe,conf). In any way for me it does not worked !?!?

You can find that I guess in the archives... On posterior mail
exchange ACC indicated 2.6.11 kernel detects the touchpad correctly,
and its tapping is just disabled by kernel in favor of software
drivers (besides some bugs related to touchpad and mouse present), but
on kernel 2.6.12 (not released yet, but I read the 1st rc change_log
and the changes required seem to be there) the tapping for the
correctly detected touchpad will be enabled again (at least that's
what I got)... To revert touchpad detection to what is detected on
kernel 2.6.10, just modify boot parameter as mentioned by ACC, it may
work as it did for inspiron 600m, or it might not as it didn't for
ACC's Vaio...
