Ideapad S10e
Used a 16GB USB flash drive for installation.
Formatted flash drive as Mac OS X Journaled Extended and at the same time copied contents of original Snow Leopard retail DVD to flash drive.
Also a must: after formatting device and copying contents, must install the latest S10 Enabler to ensure proper bootup for installing Snow Leopard.
When setting up installation, must have Enabler checked in the Customize area.
After that, installed the same latest S10 Enabler to Snow Leopard hard drive, then rebooted.
Then was able to safely update everything available in Software Update, including 10.6 directly to 10.6.2.
Ethernet doesn't work.
Wi-Fi works well.
Sound works well.
In System Preferences, under Security, must uncheck Use virtual system memory, or the system won't wake up from sleep mode.
Used application CamTwist as a workaround for getting Lenovo EasyCamera webcam to work, though it's initially out of sync with real-life movement.
