I was experimenting the same behaviour in my T410. With recent snapshots
(november) or building a new GENERIC.MP kernel after update from CVS,
the system freezes just when the boot process starts.
I can confirm that the system boots normally after activate NX. In my
thinkpad's bios the NX is located at:
Security / Memory Protection / Execution Prevent
I don't know if this behaviour is intentionally or a bug. In 5.6 stable
the system boots though NX is deactivated.
I must say too that the system is much more stable doing suspend/resume.
With 5.6 stable the system tends to hang on resume. But with current
suspend/resume works perfect.
