I can verify secure boot can be disabled and Linux Mint 14 can be installed on Asus laptops. To do so you need to turn off UEFI boot in the BIOS (or UEFI- or whatever we're supposed to call it now). I also enabled launch PXE OpRom, not sure if that makes a difference though.
Also, if you install without disabling the secure boot, the computer will not find Linux. BUT, if you boot from external media you can always select "boot from first hard drive" or something to that effect. May be a useful work around for an ARM system.
