Ugh, I was having the same problem with my 745.  So, I drug out a USB
floppy and applied the latest BIOS -- going from 2.3.1 to 2.6.2 from
Dell.  Whoops.

Starting up looks fine, all services showed OK.  Gets to local, X starts
and the box freezes at the spinning dots with a frozen mouse.  Can't
break with Ctrl-Alt-Del or Ctrl-Backspace.  

Hard power, restart, interactive init.  Allow all, but skip local.  X
starts fine.  

rc.local contains:

Reset BIOS to defaults for kicks, no change.  I have a PCI Express
graphics card, ATI x1300 installed.  


Any ideas?  I guess I can revert BIOS one by one backward to see if it
works.
