I have x60 tablet too! I have tried to install couple versions of snow leopard without any luck. I always have kernel panic. I installed leopard with "Leo4all v3" and it works fine. so which version of snow leopard that you used or how did you got your x60 tablet installed with snow leopard?? any hints will appreciate!! Thanks a lot.
I used iPortable_Snow_x86_Installer, which also has a very fine documentation of the process.
But it needs a working Mac OSX install. Both iAtkosV7 and Leo4AllV3 worked on my x60t to get up with 10.5 Leopard.
