Possibly stupid question, but what did you do with the original hda?  
disconnect completely?  disconnect power?

Are you certain your bootloader is identical?

Do you have and LVM/RAID partitions?  Moving these around can cause 
significant boot lag (like, it took me days to figure out my box wasn't just 
hanging...

Just thoughts.  Not sure what you may not be including :)  Are you running 
without quiet?  Is it a hard-lockup?  What specifics can you add?  When 
boot-issues cause a mysterious "lock", often there is some indicator, or it 
happens very soon in the boot process... which doesn't describe your problem.  
You are making it through many scripts, as you say.

Are you running an IDE drive that requires that you leave the jumper off 
completely?  Some behave strangely when the Master jumper is set.

Can you simplify the problem?  Maybe try changing to boot from runlevel 4, 
then hack up rl4 to be empty or something along those lines.
