My new laptop is x64 too.
I tried to install Mint but the laptop shut down because of the temperature (AMD is running hot).
I found on ubuntu forums one tutorial for my laptop (HP Pavilion tx2500) and they say to boot with acpi=off at boot time.
If i do this with mint, i always get Kernel panic.
I tried with other distros too, the same "kernel panic".
I believe is because all distros i tried were x86 and not x64.
I really like Mint
so, there is any pre alpha version of mint x64?
I hate Vista
so, i'm ready to install any version of x64 you guys have.
