To make the wireless of my 1001PX work in Ubuntu Lucid I had to install the 2.6.35 kernel from Kernel team PPA. The package name is linux-meta-lts-backport-maverick and it should eventually become available in the Lucid package archives.
Unfortunately, the touchpad didn't support multi-touch OOTB and the option in Mouse Settings was disabled. Here are the xinput commands I put in /etc/rc.local to get multi-touch scrolling and click emulation. They should work in other Linux OSes too:
TOUCHPAD="SynPS/2 Synaptics TouchPad" xinput set-prop "$TOUCHPAD" "Synaptics Two-Finger Pressure" 4 xinput set-prop "$TOUCHPAD" "Synaptics Two-Finger Scrolling" 1 1 xinput set-prop "$TOUCHPAD" "Synaptics Tap Action" 0 3 0 2 1 3 2
The three-finger-click doesn't work very well, so I have the bottom corners also emulating different clicks.
Now the only problem is getting the fan under control. It almost never spins up in Windows, but is constantly on in Ubuntu.
