I too can confirm this bug on a Lenovo Thinkpad t400s with Synaptics Touchpad V7.2 (using Debian though).

However, I want to add, that this does not affect xserver-xorg-input-synaptics but the Linux kernel, since the xorg driver does get it's information from there. The synaptics driver in the kernel reports the capabilities of the touchpad in hex (check dmesg). Mine are 0xd047b1. According to the Synaptics TouchPad Interfacing Guide (you can find it on the synaptics homepage) multi finger is supported when bit 1 is one. However,

 python -c 'print 0xd047b1 & (1<<1)'

prints 0 and not 2.

The question is why does it work with windows?
