touchpad problem on Sony Vaio VGN-NR498E

[Jan Hlodan <jan.hlodan@gmail.com>]

Hello,

Debian Squeeze, notebook Sony Vaio VGN-NR498E
$ uname -a
Linux 2.6.32-trunk-686 #1 SMP Sun Jan 10 06:32:16 UTC 2010 i686 GNU/Linux

Touchpad information:

$ egrep -i 'synap|alps|etps' /proc/bus/input/devices
N: Name="AlpsPS/2 ALPS GlidePoint"

Tapping doesn't work (only on touchpad buttons). Scrolling works fine.
If I try this:

# modprobe -r psmouse
# modprobe psmouse proto=imps

tapping will work but I lost scrolling function.

How I can get both function (tapping and scrolling) on the same time?
Thank you for help.

Regards,
