I've been having fun playing with this netbook and installing multiple operating systems (currently 4) on it.
At the moment it looks like this:
Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x25db3a89

OpenSolaris 2009.06 in the first partition (installed from a USB stick from the LOSUG Christmas meeting) works fine except that the network card (11ab:4354) didn't work out of the box.
But the myk driver from here worked fine and 
the instructions included with it for compiling were perfect.  Wireless and 
webcam work "out of the box". 
FreeBSD 8.0 in the second partition works fine but a few things baffled me at 
first.  In particular the need for hald_enable="YES" and 
dbus_enable="YES" as well as enabling kdm with 
ttyv8 "/usr/local/kde4/bin/kdm -nodaemon" xterm on secure" 
in /etc/ttys. 
Wireless works with a static configuration but I haven't discovered a NetworkManager equivalent.
I installed openSUSE 11.2 into the extended partition and everything works (of course :)). (Though as with Ubuntu, the OpenSolaris partition got selected as swap on the basis of its partition ID, and I had to make sure that it was definitely de-selected).
I installed the Ubuntu Netbook Remix (from a USB stick made from the ISO using 
Unetbootin) in the third partition, and this messed up the booting of 
everything else, although I chose "Advanced" and chose to "install boot loader 
to /dev/sda3".  I was trying to boot everything from the 
OpenSolaris GRUB installed in the active first partition, with generic boot 
code in the MBR.  I haven't quite worked out what happened, and I'm not 
necessarily blaming the Ubuntu installer -- I need to test this again.  But I 
had to restore the grub setup from the OpenSolaris media: 
installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c8d0s0 
And I had to use the openSUSE "repair" system to re-setup its grub - odd.
